y-intercept = (0, -32)
Explanations:From the function m(x), the y-intercept is gotten by setting x = 0 and finding m(0). m(0) gives the y-intercept for the function
The form that quickly reveals the y-intercept is:
m(x) = 4(x + 2)(x -4)
This is because it has it has been completely facorised to two linear factors
To find the y-intercept, let x = 0
m(0) = 4(0+2)(0-4)
m(0) = 4(2)(-4)
m(0) = -32
