7189607390coefficienta number that is in front of a variable A number multiplied by a variable.1
7189607391FunctionA relation for which each output has only one input. Can be tested on the coordinate plane with the vertical line test2
7189607392linearEquations that does not have any variables with an exponent. They form a lie when graphed.3
7189607393quadratic parent functiony=x^24
7189607394axis of symmetryA line that divides a parabola into two congruent reflected halves.5
7189607395vertexmaximum or minimum of a quadratic6
7189607396y-interceptA place where a function crosses the y-axis represented by b in the formula y=mx+b.7
7189607397absolute valueThe distance a number is from zero8
7189607398rangeAll possible y values of a function9
7189607399point slope form10
7189607400domainAll possible x values of a function11
7189607401whole numbersNatural numbers and zero Not negative or decimals12
7189607402scientific notationOne number is in front of the decimal. It will be multiplied by 10 to some power.13
7189607403zero exponent14
7189607404expression15
7189607405terms16
7189607406integerswhole numbers and their negatives17
7189607407coordinate planeA two-dimensional number line where the vertical line is called the y-axis and the horizontal is called the x-axis. These lines are perpendicular and intersect at their zero points called the origin.18
7189607408negative exponentNegative is the opposite of positive and division is the opposite of multiplication, so a number with a negative exponent should be moved to the denominator of a fraction and the exponent switched to positive.19
