Question

Which function has zeros at x = -2 and x = 5? ​

Answer 1

f(x) = x² - 3x - 10

(option D)

Explanation:

Answer 2

f(x) = x² - 3x - 10

Explanation:

Given zeros x = - 2 and x = 5, then the corresponding factors are

(x + 2) and (x - 5) , so

f(x) = (x + 2)(x - 5) ← expand using FOIL

= X² - 3X - 10
