• Asymptote – a line that is approached and may or may not be crossed
    • Continuous function – function whose values are continuous or unbroken over the specified domain
    • Discrete function – function whose values are distinct and separate and not connected; values are not continuous. Discrete functions are defined by their domain.
    • Domain – set of input values for the independent variable over which the function is defined
    • Exponential decay –an exponential function where 0 < b < 1 and as x increases, y decreases exponentially
    • Exponential function – a function in which the independent variable, x, is in the exponent, denoted by f(x) = abx
    • Exponential growth – an exponential function where b > 1 and as x increases, y increases exponentially
    • Horizontal asymptote – horizontal line approached by the curve as the function approaches positive or negative infinity. Horizontal asymptotes may be crossed by the curve.
    • Inequality notation – notation in which the solution is represented by an inequality statement
    • Range – set of output values for the dependent variable over which the function is defined
    • y-intercept(s)y coordinate of a point at which the relation crosses the y-axis, meaning the x coordinate equals zero, (0, y)
