Find the roots of the polynomial function f(x) = x^3 + 2x^2 + x

Ineed someone to me answer my question i have to have this done and knocked out

Hurry im being timed the graph of f(x)=x^3-3x^2+4 is shown based on the graph how many distinct real numbers solutions does the equation x^3-3x^2+4=0 have
