WOOOOOO MATHH!

1. Polynomials:

Domain: (-∞, ∞)

Range: (-∞, ∞)

**This only applies to polynomials whose highest exponent is odd.

2. Square Roots

There are three steps to finding the domain.

1. Set the inside equal to 0 and solve for x

2. Set up a number line

3. Plug in the numbers and use the non-negative intervals

Range: [vertical shift, infinity)

3. Fractions

Two steps for domain and range.

Domain:

1. Set bottom equal to zero and solve for x

2. Set up intervals

Range:

1. Take limit as x > ∞

2. Set up intervals

4. Absolute value

Domain: (-∞, ∞)

Range: [shift, ∞) or (-∞, shift]
