Question

Which polynomial function has zeros at −4, 3, and 5?

a. f(x) = (x + 4)(x + 3)(x + 5)
b. g(x) = (x + 4)(x – 3)(x – 5)
c. h(x) = (x – 4)(x – 3)(x – 5)
d. k(x) = (x – 4)(x + 3)(x + 5)

Answer 1

Answer: B

Answer 2

The answer to your question is letter B

Explanation:

a. f(x) = (x + 4)(x + 3)(x + 5) The zeros of this polynomial are x = -4, x = -3 and x = -5, so this polynomial is not the right answer,

b. g(x) = (x + 4)(x – 3)(x – 5) The zeros of this polynomial are x = -4, x = 3, x = 5, so this polynomial is the right answer.

c. h(x) = (x – 4)(x – 3)(x – 5) The zeros of this polynomial are x = 4, x = 3, x = 5, so this polynomial is not the right answer.

d. k(x) = (x – 4)(x + 3)(x + 5) The zeros of this polynomial are x = 4, x = -3, and x = -5, so this polynomial is not the right answer.
