Answer:
The only thing you will do is to plug the x in the equation.
x = -2 ---> f(x) = -6
x = 0 ---> f(x) = 0
x = 3 ---> f(x) = 9
x = 7 ---> f(x) = 21
f(x) = 3x
f(-2) = <u>3(-2)</u>
f(-2) = -6
f(0) = <u>3(0)</u>
f(0) = 0
f(3) = <u>3(3)</u>
f(3) = 9
21 = 3x
<u>21 / </u><u>3</u> = <u>3x / 3</u>
7 = x
Hope this helps, thank you :) !!

Answer:
0,12
Step-by-step explanation:
The y goes up by 5. So, if the 12 is y then the x is 0. Y-Intercept is the y coord when x is 0. 12=y then 0=x. So, 0,12. But, if 12y is 1x, then it is 0,7. (12-5=7) But, I think that it is 0,12
Answer:
Step-by-step explanation: for you to get the answer you have to understand that 3 to 1 means to multiply by 3 so 45x3=135
