+9+
-12+
-15-
f(x)
4 5 6 7 x
What is f(0)?
O 12 only
O2 and 3 only
O-2,-1, 1, and 2 only
O-2, -1, 1, 2 and 12

Answer 1

f(0) = 12 only

Explanation:

f(0) means what is the value of y when x = 0

locate x = 0 on the x- axis , at the origin, go vertically up to intersect with the point (0, 12 ) , then

when x = 0 , y = 12 , that is

f(0) = 12 , only
