Question 987566: Give the x-intercepts, the table of signs and the sketch of the graph.
f(x) = (x + 3)^2 (x + 1)^3

f is shown in factored form. x-intercepts are -3 and -1.

INTERVAL                   
SIGN CHECK     (-)^2(-)^3         (+)^2(-)^3     (+)^2(+)^2
SIGN           (-)                (-)             (+)

f changes signs and crosses the x-axis at x=-1 but just touches the x-axis at x=-3.
