Given the quadratic function f(x) = (x + 6)(x – 3):

Harlamova29_29 [7]

Answer:

Step-by-step explanation:

Given quadratic function is,

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

For x-intercept,

Substitute the value f(x) = 0.

(x + 6)(x - 3 = 0

x = 3, -6

So the x-intercepts will be,

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

For y-intercept,

Substitute the value for x = 0,

f(0) = (0 + 6)(0 - 3)

= -18

Therefore, y-intercept of the given quadratic function will be (0, -18).
