CPM Homework Help : A2C Problem 9-8

For each equation below, make tables that include x-values from −2 to 2 and draw each graph. Homework Help ✎
1. y = (x − 1)²(x + 1)
2. y = (x − 1)²(x + 1)²
3. y = x³ − 4x
4. What are the parent functions for these equations?

Answer (a):

Answer (b):

Hint (c):

Use the same method as in parts (a) and (b).

Hint (d):

What is the highest-valued exponent?

Example (d):

The parent function is y = x³.
y = (x − 1)²(x + 1)
y = (x² − 2x + 1)(x + 1)
y = x³ − x² − x + 1
