Question

Which of the following functions is graphed below?

Answer 1

Answer: B

Step-by-step explanation: The answer is B

Answer 2

C (see attached)

Explanation:

The linear portion of the graph is defined for x ≥ 1, with the point x=1 included. Only selections A and C do that.

The quadratic portion of the graph is defined for x < 1. Only selection C does that. (Selection A is doubly-defined for x > 1, so is not a function. It is undefined for x < 1.)
