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:
6
Step-by-step explanation:
You will recognize that these points both have the same x-coordinate, so are on the vertical line x=2. The distance between them will be the difference of the y-coordinates:
6 - 0 = 6
The points are 6 units apart.
__
If you like, you can use the distance formula.
d = √((x2 -x1)² +(y2 -y1)²)
The values of these parameters are ...
x1 = 2, y1 = 0
x2 = 2, y2 = 6
Then the distance is ...
d = √((2 -2)² +(6 -0)²) = √(0 +36) = 6
The distance between the points is 6 units.
The answer is 5,3,3 in that order, you can do this using the point slope formula
Lol i need easy math too !!!
