Math 10 Week #13

This week we learnt how to write function notation as well as find an answer to a equation written in function notation.

You might start with an equation that looks like this: f(x)=3x+6

The question will most likely tell you that x equals a certain number. So, we’ll say that x=4

Next, you replace the 4 with any spots that say x so the equation is now f(4)=3(4)+6

Now, you can solve the equation.

f(4)=3(4)+6

f(4)=12+6

f(4)=18
