Answer:

f(3) = 2 or (3, 2)

The y-value we solved for is 2.

Explanation:

The equation they give you, all you need to do is plug in the x-value they give you.

f(x) the y-value in (x, y)

it will be on that bold, vertical line on the graph

2=3x-7

add 7 to both sides

9=3x

divide both sides by 3

x=3

y=2
