Week 12 – Math 11 – Graphing absolute values

December 2, 2018 gavinp2016 Leave a comment

in this week we learned how to graph absolute values

for the first example a linear line y=|x+3|

so first you just graph the parent function y=x+3

when it touches the x-intercept it has to go back up because it always has to stay positive

the right side stays the same because it’s positive and the left side just flips making a v shape

we also learned the absolute value of parabolas, for example, y=|x^2 -3|

so you want to draw the parent function again and just flip the negative parts so they are positive making a w shape

WEEK 11 – MATH 11 – GRAPHING QUADRATIC inequalitys

November 22, 2018 gavinp2016 Leave a comment

This week we learned how to solve quadratic inequalities.
to do this we graph a regular quadratic just as we learned before
then to find out what side is true its if the Y is greater than, shade in the center if its Y is less than, then shade the outside.

WEEK 10 – MATH 11 – GRAPHING INEQUALITYS

November 22, 2018 gavinp2016 Leave a comment

In this week we learned how to graph an inequality.
Say we have 2x + 3y > 6

First, we must make the Y a 0
2x > 6
Then we must divide both sides by 2
x > 3
Then change the > to a =
x = 3
we then repeat the same steps for the Y axis to end up with
y = 2

Once you have these two points plot both on the grid and connect them. after this follow the line to reach each side of your graph.

Next, we must figure out which side is true. to do this we must replace the 2x + 3y with a 0 so we end up with
0 > 6
Now we ask our self, is 0 greater than 6?
since its no, the shaded side will be the side without 0 on it.

WEEK 9 – MATH 11 – GRAPHING ADVANCED TRINOMIALS

In this week we learned how to graph trinomials quicker

for example in this equation
y = 2X^2 + 6X + 8
first of in this equation you can see the Y-axis (8)

Once you find the Y axis you can then convert it to…

y = 2(X + 3)^2 -1

This one shows the vertex (-3,-1) and tells you where the formula will shape and point (2) it shows by looking at the “a” (2).

WEEK 8 – MATH 11 – GRAPHING TRINOMIALS

November 5, 2018 gavinp2016 Leave a comment

In this week we learned how to graph trinomials.

if the graph is Y=X^2
notice how this graph has its axis at (0,0) and how it is going up 1,3,5

if the graph is Y=X^2 +2
The + 2 makes the parabola just go up to spaces so the axis is now (0,2) and still has the same pattern 1,3,5

if the graph is y= (x-2)^2
the -2 means to go to the right 2 so its the opposite of the symbol to which side you go so if it was +2 you would have gone 2 to the left

if the graph is y=2x^2
the 2 in front of the x makes it stretched out upwards because before there is an imaginary 1 in front of the x and now its 2 so it goes from 1,3,5 to 2,6,10 which makes the graph look skinner

WEEK 7 – MATH 11 – FACTORING TRINOMIALS

November 5, 2018 gavinp2016 Leave a comment

In this week we learned how to factor Trinomials

For example 16X^2 + 36X + 8

First, multiply 16 * 8 and find the factors of numbers that multiply towards it until you find the factors that add together to create 36.

So 16 * 8 = 128
128 = 4 * 32
4 + 32 = 36

so once you have done this you will end up with 4X and 32X in your empty squares.

and finally, you will end with (4 + 32X) and (4X + 8).

Week 6 – Math 11 – Solving Trinomials

October 15, 2018 gavinp2016 Leave a comment

In this week we learned how to balance trinomials, to do this we use this formula,

$X=$ $\frac{-B \sqrt{(b)^{2}-4(a)(c)}}{2(a)}$

so lets say we have this as our equation,
$3X^{2} + 8X + 24=0$

first we must identify A, B and C,
$3$ is A
$8$ is B
$24$ is C

So using these values we must replace them in the spots of the formula with the matching letters,
$X=$ $\frac{-8 \sqrt{(8)^{2}-4(3)(24)}}{2(3)}$

Now we will evaluate the equation,
$X=$ $\frac{-8 \sqrt{64-288}}{6}$
then,
$X=$ $\frac{-8 \sqrt{-224}}{6}$

after you get to this point we must find a common factor to divide everything with,
$X=$ $\frac{-8 \sqrt{-224}}{6}$ $/$ $\frac{2}{2}$

Giving us,
$X=$ $\frac{-4 \sqrt{-56}}{3}$

simplified again,
$X=$ $\frac{-4 -2\sqrt{14}}{3}$

and that’s the final answer!

WEEK 5 – MATH 11 – Simplifying Binomials and Trinomials

October 15, 2018 gavinp2016 Leave a comment

This week we learned stuff along the lines of CDPEU and other stuff to help us simplify binomials and trinomials.

for example,

lets say I have something that looks like this,
$(X)^{2}-16=0$

this binomial would look somehing like this once it is simplyfied
$(X+n)(X-n)=0$

Now, what time what makes 16,
$4$
So it would look like this
$(X+4)(X-4)=0$

$X * X=(X)^{(2)}$
$4 * -4=-16$
$X * 4=4X$
$X * -4=-4X$

once you combine all of these you get,
$(X)^{(2)}-16=0$

Fear Photo

Time, used to measure the speed of matter, and with time brings future and past. in the future there are dates and with dates brings stress, anxiety, anger, and sadness. all these emotions ultimately lead to Fear. fear can also be a force used to manipulate others, giving those manipulating power. fear can also be something that brings others together to take down or defeat something bigger than all of them. to me, fear is like being scared, disrupted, and full of anxiety. fear to me is being scared of something and not wanting to face it. this photo shows a date of a test, marking the day and time. this photo causes me lots of anxiety and fear as I prepare for the fateful day when its the date. this gives fear and anxiety because I have to be prepared and get a high grade which can be hard to do. I think I could fix this by either not caring about the test and what I get and just giving it my all, or I could be extremely prepared and get ready to ace it.
