Study Notes

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
