Y-Intercept The y-coordinate(s) of the point(s) where a graph intersects the y-axis. Linear Function A function that can be written in the form y=mx+b, where x is the independent variable and m and b are real numbers. Its graph is a line. Rate A ratio that compares two quantities measured in different units. Rate of Change A ratio that compares the amount of change in a dependent variable to the amount of change in an independent variable. Slope A measure of the steepness of a line. Exponent The number that indicates how many times the base in a power is used as a factor. Exponential Expressions An algebraic expression in which the variable is in an exponent with a fixed number as the base. Exponential Function A function in the form f(x)=ab^x where a and b are real numbers, a does not equal zero, b0, and b does not equal 1. Perfect Square A number whose positive square root is a whole number. Exponential Growth An exponential function in the form y=a(1+r)^t, where r is the rate of growth, a is the initial amount and t is the time. Exponential Decay An exponential function in this form, where r is the rate of decay, a is the initial amount and t is the time. Base The number in a power that is used as a factor. Half-life The half-life of a substance is the time it takes for one-half of the substance to decay into another substance. arithmetic sequence A sequence whose successive terms differ by the same nonzero number, called the "common difference". common difference In an arithmetic sequence, the nonzero constant difference of any term and the previous term. dependent variable The output of a function; a variable whose value depends on the value of the input, or independent variable. domain The set of all inputs (generally x-values) of a relation or function. function A relation in which ever domain value is paired with exactly one range value. function notation If x is the independent variable and y is the dependent variable, than the function can be written as f(x), where f names the function. independent variable The input of a function, a variable whose value determines the value of the output, or dependent variable. range The set of all outputs (generally y-values) of a relation or function. sequence A list of numbers that often form a pattern.
