4-141.
  1. Find the coordinates of the intercepts for each of the following functions: Homework Help ✎

    1. g(x) = (x + 3)3

    2. y − 1 = 3x

y-intercept where x = 0:

g(0) = (0 + 3)3

g(0) = 27

x-intercept where g(x) = 0:

0 = (x + 3)3

−3 = x

The y-intercept is at (0, 27).
The x-intercept is at (−3, 0).

See part (a).
