explain how to sketch a graph of the function f(x) = x3 + 2x2 – 8x. be sure to include end-behavior, zeroes, and intervals where the function is positive and negative.

The degree of the function is odd and the leading coefficient is positive – so the function goes to negative infinity as x goes to negative infinity and to positive infinity as x goes to positive infinity.

The zeroes are –4, 0, and 2, all with multiplicity 1.

The function is negative from negative infinity to –4 and from 0 to 2.

The function is positive from –4 to 0 and from 2 to infinity.
