  • Logarithm
    Inverse operation to exponentiation, revealing the power a base must be raised to for a given result.
  • Exponential Function
    Mathematical relationship where a constant base is raised to a variable exponent, producing rapid growth or decay.
  • Logarithmic Function
    Function expressing the exponent needed for a base to yield a specific value, mirroring exponential functions.
  • Base
    Constant value in exponentials and logarithms that is repeatedly multiplied or used as the reference for powers.
  • Exponent
    Number indicating how many times a base is multiplied by itself in exponential expressions.
  • Logarithmic Form
    Equation format showing the exponent required for a base to reach a certain value, typically written as log_b(x).
  • Exponential Form
    Equation format where a base is raised to an exponent to produce a value, such as b^x = m.
  • Inverse Function
    Function that reverses the effect of another, such as logarithms undoing exponentials and vice versa.
  • Common Logarithm
    Logarithm with base 10, often written simply as log(x), and widely used in scientific calculations.
  • Natural Logarithm
    Logarithm with base e, denoted as ln(x), frequently appearing in calculus and continuous growth models.
  • Reflection
    Graphical transformation where a function's graph is flipped over a line, such as y = x for exponentials and logarithms.
  • Vertical Asymptote
    Line that a graph approaches but never touches, such as x = 0 for logarithmic functions.
  • Domain
    Set of all possible input values for a function, for logarithms typically all positive real numbers.
  • Range
    Set of all possible output values for a function, for logarithmic functions usually all real numbers.
