Answer:
y- intercept = 8
Step-by-step explanation:
given
f(x) = - (x - 2)(x + 4)
The y- intercept is the point on the y- axis where f(x) crosses it.
the x- coordinate of any point on the y- axis is 0
substitute x = 0 into f(x)
f(0) = - (0 - 2)(0 + 4) = - (- 2)(4) = - (- 8) = 8
The y- intercept is 8 or (0, 8 ) in coordinate form
