Question

Graph the function f(x) = x3 – 3x – 2. Based on the graph, which value for x is a double root of this function? =-1

Answer 1

f(x) = -4x^3 + 52x + 48

Explanation:

The polynomial function with zeros at -3, -1, and 4 and f(-2) = -24 is:

f(x) = -4x^3 + 52x + 48

This can also be written in factored form as:

f(x) = -4(x + 3)(x + 1)(x - 4)
