More concepts to explore

  • Exponential functions

    An exponential with positive base other than one models multiplicative change.

  • Function transformations

    Translations, scalings and reflections change a graph through controlled changes of its formula.

  • Absolute value

    Absolute value measures distance from zero on the real line.

  • Algebraic expressions

    Expressions combine constants, variables and operations without necessarily asserting an equation.

  • Arithmetic operations

    Addition, subtraction, multiplication and division follow precedence rules; division by zero is undefined.
