Question

Which point is an x-intercept of the quadratic function f(x)=(x+6)(x-3)?

Answer 1

Option D. (-6, 0) is correct and this is on edge 2021

Answer 2

Intercept: -6,0

f(x)=(x+6)(x-3)

Change the function to an equation:

y = (x + 6)(x - 3)

When y = 0:

x + 6 = y

x + 6 = 0

x = 0 - 6

x = -6

x - 3 = y

x - 3 = 0

x = 0 + 3

x = 3
