Question

Which of the following represents the zeros of f(x) = x3 − 11x2 + 38x − 40?

Answer 1

2,4, and 5 are the answers.

Answer 2

The function represent a polynomial so its graph is a curve.

f(x) = x3 − 11x2 + 38x – 40

it alternate form can be

f(x) = (x -5) ( x – 4) (x – 2)

so the roots of the eqution are

x = 2

x = 4

x = 5
