Question

6. What is the equation for the graphed piecewise function?

Answer 1

Answer:

  D

Step-by-step explanation:

The open circle at the origin means the rightmost piece will have domain x > 0. That is only the case in choices C and D.

The middle piece has a negative slope. That is only the case in choice D.

The appropriate piecewise function is ...

  $f(x)=\begin{cases}-2,&\text{for }x\le-3\\-x+4,&\text{for }-30\end{cases}$
