Answer:
all x intercepts [-4, 0] [4, 0]
Step-by-step explanation:
x-intercept, i.e. y=0
f(x) = x^3 - 4x^2 - 16x + 64 = 0
(x^3 + 4^3) - 4x^2 - 16x = 0 [FYI, x^3 + y^3 = (x + y)(x^2 - xy + y^2)]
(x + 4)(x^2 - 4x + 16) - 4x^2 - 16x = 0
(x + 4)(x^2 - 4x + 16) - 4x(x + 4) = 0
(x + 4)(x^2 - 4x + 16 - 4x) = 0
(x + 4)(x^2 - 8x + 16) = 0
(x + 4)(x - 4)^2 = 0
x = -4 or 4
all x intercepts [-4, 0] [4, 0]

Step-by-step explanation:
Answer:
y = -3/2x + 3
Step-by-step explanation:
First, know that slope-intercept form is y = mx + b. Since our y-intercept is 3, we can plug that in for B, and since the slope goes down 3 and over to the right 2, it is -3/2. So, when everything's plugged in, we get y = -3/2x + 3.
