Which is the correct graph of f(x) = x3 – 10x2 + 9x

Ok

we see the leading coefient is positive, and the degre is 3 so it goes from bottom left to top right

if we factor to find x intercepts or zeros we get f(x)=(x)(x-9)(x-1)
so it crosses at x=0,1,9
that would be the 4th graph (the one that goes down to y=-90)

He secknd step was the answer to them
