FACTOR integers that multiply together to make a given product


Example:    2   and 5   are factors of  10.

FRACTION a way of expressing the division of numbers by stacking one over the other


Example:


FUNCTION a relationship between a set of inputs (x-values) and a set of outputs (y-values)
Example: f(x) = 4 − x


HISTOGRAM a graphical representation of numerical data; also known as a bar graph
IMAGINARY NUMBER the square or any other even root of a negative number INCLUSIVE
including any two endpoints


INDIRECT PROPORTION (INVERSE VARIATION) a proportion in which one variable increases
as another variable decreases, or vice versa Example: It takes Mrs. Smith 30 minutes to drive
to school if she drives at 30 miles per hour. If she drives 60 miles per hour, it takes her only 15
minutes.

INTEGER any real number except decimals or fractions (including 0) ISOCELES (TRIANGLE)
A triangle in which two sides are equal. The two angles opposite the equal sides are also equal.


LINEAR FUNCTION a function that, when graphed, produces a straight line Example: The
slope-intercept form of a linear equation is y = mx + b.


LINEAR GROWTH a condition in which variables increase at a steady rate, as shown in the
graph below
