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 :)
+434 Thank you, but I was curious how would one would derive the answer, as such?
+36916 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
+128475 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
+434 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!
+434 I'm curious XD if I missed something extemly important, or I I'm correct XD
+128475 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
+434 Thanks, but it's outside of my acess aka my parental restrictions won't let me acess it.
+794 ohh dang dont worry im on school restriction but i have no parintal restriction because my parents don't know how and i aint tellin' them ethier
+434 XD No it's fine, I don't have a proiblem with the restrictions, I get along pretty mcuh as every other kid does.
