exponential function {Ans: a function of the form f(x) = ab^x, where a and b are real numbers with a ≠ 0, b>0, and b ≠ 1}inflection point {Ans: The point on a curve at which the curves concavity changes; also called the point of inflection}Interpolation {Ans: A method of inserting new data points in the range of a known set of data points}inequality {Ans: A mathematical sentence that shows the relationship between quantities that are not equivalent}Global Maximum {Ans: Finds the highest y-number the function goes to}qualitative variable {Ans: A variable that is not numeric; also called a categorical variable, a qualitative variable describes data that fits into categories}quantitative variable {Ans: a characteristic that can be measured numerically}common ratio {Ans: The number by which each term in a sequence is multiplied to find the next number in the sequence; for example 4 is the common ratio for the sequence [1, 4, 16, 64, 256...]}ordered pair {Ans: A pair of numbers that give the location of a point on a x and y grid. for example graph (3, 2)}inverse function {Ans: a function that "undoes" what the original function does}
