Question

The piecewise function f(x) is graphed below. What is the value of f(5)?

f(5) = –1
f(5) = 3
f(5) = 5
f(5) is undefined

Answer 1

a is the corresct answer

Explanation:

Answer 2

In this piecewise function, f(5) = -1.

In order to find which 5 to use when it is a point that is graphed twice, always look for the closed circle. The open circle means not included, whereas the closed circle means also included. Since the closed circle is at -1, then we know that is the value of f(5).
