Answer
(a) $f(-4)=-2, g(3)=4$
(b) $x=-2$ or $x=2$
(c) $x=-3$
(d) $[0,4]$
(e) $[-4,4]$, $[-2,3]$
(f) $[-4,3]$, $[0.5,4]$
Work Step by Step
(a) by looking at the graphs of f and g
$f(-4)=-2, g(3)=4$
(b) by looking at the graphs of f and g
when $x=-2$ or $x=2$ => $f(x)=g(x)$
(c) by looking at the graphs of f
$f(x) = -1$ when $x=-3$
(d) the function f is decreasing in $[0,4]$
(e) the function f:
the domain is $[-4,4]$
the range is $[-2,3]$
(f) the function g:
the domain is $[-4,3]$
the range is $[0.5,4]$
