The difference of the third and the first quartiles of the data set, representing the middle half of the data.

A function of the form f\left(x\right) = ab^x , where a and b are real numbers with a \ne 0, b> 0, and b \ne 1

A polynomial with three terms

An equation in the form ax^2+bx+c=0, where a, b, and c are real numbers and a\ne0.

Ax+Bx=C where A, B, and C are constants and A and B are not both 0

The y-value of the highest point on the graph of the function.

A method used by solving one variable and substituting the resulting expression into the other equation(s).

A bar graph used to display data grouped in class intervals. The width of each bar is prop. to the interval.

Two inequalities that are combined into one statement by the word and or or.

The part of the coordinate plane on one side of a line, which may include the line.

The highest or lowest point in a parabola

A number or a product of numbers and variables with whole-number exponents, or a polynomial with one term.

A polynomial in one variable is written in standard form when the terms order from greatest degree to least degree.

h=-16t^2+vt+s, where v is initial velocity in feet per second and s is the starting height in feet.

The formula x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}, which gives solutions, roots all in the form of ax^2+bx+c=0
