2. Graph and label each of the given points on the coordinate axis.
A = (0, 0)
B = (0, 5)
C = (2, 3)
D = (−1, 4)
E = (7, −2)
F = (−9, 1)
3. Here is the graph of a function.
(a) Determine whether each of these points lies on the graph.
(0, 1)

(-2, 3)
(2, - 21 )
(-1, 3)
(-4, -1)
(b) Recall that in function notation, f (3) refers to the y-value of the function at x = 3.
Use the graph to find the following values for the given function:
f (-3) =
f (-2) =
f (-1) =
f (0) =
f ( 23 ) =
f (3) =
(c) What x-values produce each of the following function values?
f (x) = 0
f (x) = 1
f (x) = -2
