Question

The graph of a function f(x) is shown. What is the value of x where f(x) = -5? And f(0)?

Answer 1

x = -3 when f(x) = -5

f(0) = 3

Explanation:

When f(x) = -5, that means they have told you the y value. When y = -5, x = -3.

If the number is in the parentheses of the function, they are giving you the x value. When x = 0, y = 3
