Algebra 2 Domain and Range Practice

Linear Functions

• Domain: All real numbers
• Range: All real numbers

Quadratic Functions

• Domain: All real numbers
• Range: [0, ∞), indicating outputs never go below zero

Absolute Value Functions

• Domain: All real numbers
• Range: [0, ∞), outputs are always non-negative

Square Root/Radical Functions

• Domain: [0, ∞), only non-negative inputs are allowed
• Range: [0, ∞), outputs are also non-negative

Exponential Functions

• Domain: All real numbers
• Range: (0, ∞), outputs approach zero but never reach it

Logarithmic Functions

• Domain: (0, ∞), inputs must be positive real numbers
• Range: All real numbers, can output any real value

Rational Functions

• Domain: All real numbers except for zero (denominator cannot be zero)
• Range: All real numbers except for zero (outputs cannot equal zero)

Cubic Functions

• Domain: All real numbers
• Range: All real numbers, can output any value

Semicircle Functions

• Domain: [-1, 1], defined between -1 and 1 inclusively
• Range: [0, 1], outputs are constrained between 0 and 1 inclusively

Greatest Integer Functions

• Domain: All real numbers
• Range: Integers only, outputs are restricted to whole numbers
