Question

The function f(x) is shown on the graph.

What is f(0)?

0 only
-6 only
-2,-1,1, and 3 only
-6,-2,-1,1,and 3 only

Answer 1

Answer: -6 only (choice B)

This is because the point (0,-6) is on the blue line. This is the y intercept.

Choice C would be true if you wanted to solve f(x) = 0, instead of f(0) itself.

Answer 2

-6

Explanation:

f(0) means what is the output when the input is 0

x=0 y= -6
