Question

Can someone explain to me step by step how to solve this? I have like 10 of them.

Answer 1

Solve what?

Answer 2

This. if someone can just walk me through this one I can solve the other 10, I think

Answer 3

f(x)=4, that basically just means when y=4, so (0,4) and (3,4)

f(2) means when x=2, so (2,1)


At least I'm 98% that's right, if not i feel stupid

Answer 4

so is it just where the line intercepts??

Answer 5

@potatoBucket is absolutely correct
please refer to the attached

Answer 6

"so is it just where the line intercepts??"
@AwesomeAries coordinates are always made up of 2 values, an x and a y (x, y)

so all it's asking is to find the corresponding value when the line (blue) reaches the given value.

so f(x) = y
if f(x) = 4, then y = 4, so at what x values does our y value marry up with this?
refer to the orange points on the graph

Answer 7

I did the other 10 like this last night just wanted to make sure I got the concept thank you both.
