I'm given the function.

\(F(-2) =\)

and I have the following point's on the graph (Since Webcalc's having a problem with uploading pictures)

* THE FOLLWOING POINTS: *(1, -2), (0. 1), (-2, 2), (-3, 0);

My answer for the question was 1 but I appread incorrect my judgement was based on how all my other problem's, when they would tell what x was and ask what F(x) was so I tried the opposite for this.

**THANKS SO MUCH GUYS FOR YOUR HELP :)**

Thank you, but I was curious how would one would derive the answer, as such?

Ya just have to 'derive' it from the information given and an understanding of what functions (f(x))= .... mean unless you are actually GIVEN the function like (for example) f(x) = x^2 +3x -1

F(-2) actually asks..."When we put "-2" into "F".....what is the resulting y value???"

Look at the points (x , y)....note that we have the point (-2, 2)

This means that when we put -2 into F, we get get 2 as a result

So

F(-2) = 2

OOOOOh so basically with the given point's it's asking if X or F('x') is equal to -2, we cehck our points to see which x is equal to negative 2 then check the Y value?

Thanks for answering this quick!

I'm curious XD if I missed something extemly important, or I I'm correct XD

You didn't miss anything

F(x) = y

So

F(-2) = y ???

So (x, y) = (-2, y) and the point with an x coordinate of -2 has a y coordinate of 2

So

f(-2) = 2
