Question

The graph of f(x) is shown. What is the value of x when f(x) = 4?

A) -4
B) -3
C) 4
D) 3

Answer 1

The value of x when f(x) = 4 is 3

Using the parameters given :

• f(x) = 4

The value of f(x) is 4 refers to the value of y on the graph. To obtain the value of x when f(x) is 4 , we locate the value of y = 4 on the y - axis and then take the corresponding value of x on the x-axis .

The value of x when y = 4 is 3.

Therefore, the value of x is 3.
