### Lesson 6

- I can identify features of polynomials and their graphs using their standard and factored forms.

### Lesson 7

- I can write an expression for a function that has specific horizontal intercepts.

### Lesson 8

### Lesson 12

- I can divide one polynomial by another.

### Lesson 13

- I can use long division to divide polynomials.

### Lesson 14
