Question

What are the zeros of the function?

Answer 1

Answer:

The third choice:  -4, 0, and 1

Step-by-step explanation:

Finding zeroes is another way of saying solve...set the equation equal to zero and solve..

0 = 2x³ + 6x² - 8x

0 = 2x(x² + 3x - 4)    (factor out a 2x from all three terms)

0 = 2x(x + 4)(x - 1)       (factor x² + 3x - 4)

So

2x = 0          then x = 0

x + 4 = 0      then x = -4

x - 1 = 0       then x = 1

Our zeroes are -4, 0, and 1
