Answer
See upper graph.
vertical asymptotes $x=\pm1$
x-intercepts $\pm1.6$
y-intercepts $-4$
local maximum $(0,-4)$
end behavior: $y=-x^2$, see lower graph.
Work Step by Step
See upper graph.
vertical asymptotes, $x=\pm1$
x-intercepts $\pm1.6$
y-intercepts $-4$
local maximum $(0,-4)$
end behavior: use long division (shown in the middle figure),
we find the quotient $y=-x^2$ that has the same end behavior as the rational function, see lower graph.
