Answer
(a) $x=-4$ and $y=0$
no x-intercept, y-intercept= $3/4$
domain and range {$x|x\ne-4$}, {$y|y\ne0$}
(b) see graph, domain and range {$x|x\ne-4$}, {$y|y\ne0$}
Work Step by Step
(a) vertical and horizontal asymptotes $x=-4$ and $y=0$
x- and y-intercepts: no x-intercept, y-intercept= $3/4$
domain and range {$x|x\ne-4$}, {$y|y\ne0$}
(b) see graph, domain and range {$x|x\ne-4$}, {$y|y\ne0$}
