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

(-6, 0) and (3, 0).

Step-by-step explanation:

There are actually 2 x-intercepts. You will get the x-intercept when f(x) = 0.

f(x) will equal 0 when either (x + 6) = 0 or (x - 3) = 0.

x + 6 = 0

x = -6

x - 3 = 0

x = 3

So, your two x-intercepts will be at (-6, 0) and (3, 0).

Hope this helps!
