?

A. 5
B. 16
C. function is not defined for this value
D. 9

Answer 1

9

Explanation:

Answer 2

The function is defined piecewise, and 4 does not fall under any of the conditions where the function is defined. Therefore, the function is not defined for x=4.

So the answer is C, "function is not defined for this value."
