x and y intercept of y=x^3+7x^2+10x

college algebra  Reiny, Wednesday, April 1, 2009 at 11:51am
for the xintercept let y = 0
x^3 + 7x^2 + 10x = 0
x(x^2 + 7x + 10) = 0
x(x+2)(x+5) = 0
so x = 0, 2, 5
(your xintercepts)
for the yintercept, let x = 0
then of course y=0
so 3 xintercepts, one yintercept
