Question

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

Answer 1

D (-6,0) is the correct answer

Answer 2

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

Explanation:

we have the function
`f(x)=(x+6)(x-3)` and the x-intecept of the function will be when y=0 then:

`f(x)=(x+6)(x-3)\longrightarrow 0=(x+6)(x-3)`

Then the result will be 0 when x=-6 or x=3
