Question

(X-7)(x+3) y intercept

Answer 1

Answer: coordinates of the y-intercept is (0, -21)

Explanation:

I'm assuming that you are asking for the coordinates of the y-intercept of the function

f(x)=(x-7)(x+3).

Well the y-intercept occurs when x=0, so plugging this value into f(x) yields f(0)=(-7)(3)=-21.
