Answer
a) $f(-4)=-2$, $g(3)=4$
b) $x=-2$, $x=2$
c) $x=-3$, $x=4$
d) $0\lt x\leq4$
e) Domain of $f$: $-4\leq x\leq 4$, range: $-2\leq y\leq 3$
f) Domain of $g$: $-4\leq x\leq 3$, range: $0.5\leq y\leq 4$.
Work Step by Step
"State" questions require an exact answer whereas "estimate" questions require an approximation.
We have:
a) $f(-4)=-2$, $g(3)=4$
b) $f(x)=g(x)$ for $x=-2$, $x=2$
c) $f(x)=-1$ for $x=-3$, $x=4$
d) $f$ is decreasing for $0\lt x\leq4$
e) The domain of $f$ is $-4\leq x\leq 4$, while the range is $-2\leq y\leq 3$
f) The domain of $g$ is $-4\leq x\leq 3$, while the range is $0.5\leq y\leq 4$.
