Week 13- Quadratic and Reciprocal Functions

During this week we learned we can have a lot of weird graphs from reciprocal functions.

The steps you sut follow to find the graphs are.

1. Graph line

2. Find the invariant points (which are found at y= 1 and y= -1)

3. Find asomptotes

 

There are 3 Diffrent graphs you can get

  1.  You can have a graph with 2 x values

This happens when the parabola passes through the 1 or -1 y intercepts

this graph is $latex y=x^2$ and it’s reciprocal one

 

And in this graph the x values are:

1. x= 1

2. x= -1

 

 

2. You can have a graph with  4 x values

This happens when the parabola passes through the -1 and 1 y intercepts

this graph is x^2-4 and it’s reciprocal one

And in this the x values are:

1. x= -1.7

2. x= 1.7

3. x= -2.2

4. x= 2.2

3. You can have a graph with 0

this happens when the parabola doesn’t go passed the 1 or -1 y intercepts

this graph is y=x^2 +2 and it’s reciprocal one

there are no x values found.
