Question

the graph of a function f is shown below. find f(2) and find one value of x for which f(x)=4.
(a) f(2)=
(b) one value of x for which f(x)=4:

Explanation:

Step1: Find f(2)

Locate x = 2 on the x - axis. Then, find the corresponding y - value on the graph of the function.

Step2: Find x when f(x)=4

Locate y = 4 on the y - axis. Then, find the corresponding x - value(s) on the graph of the function.

Answer:

(a) [The y - value at x = 2 from the graph]
(b) [The x - value at which y = 4 from the graph]
