Question

Find the y-intercept of the cubic f(x)=(x-2)(x+1)(x-3)

Answer 1

y_intercept = (-2)*(1)(-3) = 6

Answer 2

Y intercept is the point where the curve f(x) meets the y axis. For any curve substituting x=0 will give you the Y intercept. And substituting x=0 gives the X intercept. Try it yourself! :)
