Question

A quadratic function is given as..... Which of the following is a zero of the function?

Answer 1

The last (7, 0)

Explanation:

Zeros are x-axis intercepts therefore y=0, so it's always (x, 0)

{For given function:

(x - 3)² - 16 = 0

(x - 3)² = 16

x - 3 = 4 or x - 3 = -4

x = 7 or x = -1

Zeros: (7, 0) and (-1, 0)}
