TL;DW: Mastering the y-intercept is one of the easiest ways to start graphing any polynomial! In this 35-second tutorial, we walk through exactly how to find the y-intercept of the cubic function f(x) = (x - 1)^3 + 8.

The rule is universal: the y-intercept always occurs where x = 0. We evaluate f(0) step-by-step, including a quick reminder on why an odd number of negative factors results in a negative product.

Key Steps in this Short:

Set x = 0 to find f(0).

Simplify the expression: (0 - 1)^3 + 8.

Calculate the power: (-1)^3 = -1.

Result: -1 + 8 = 7.

Rounding out your intercepts helps confirm the vertical and horizontal shifts of your graph! For the full Precalculus Exam 1 review covering Polynomial and Rational functions, check out the long-form video here:    • Precalculus Exam 1 Review (Unit 3): Polyno...
