Answer
$a) f(-1)=-1 \\ b) f(0)=0 \\ c) f(1)=5 \\ d) f(3) =11$
Work Step by Step
In order to find $f(-1), f(0), f(1), f(3)$, we will plug in the $x$ values into the piece of the graph whose interval includes that $x$ value.
$a) f(-1)=(-1)^3=-1 \\ b) f(0)=(0)^3=0 \\ c) f(1)=(3)(1)+2=5 \\ d) f(3) =(3)(3)+2 =11$
