Algebra 1 Test 6

Vocabulary

A

Associative Property- (a + b) + c = a + (b + c)

B

Binomial – two terms

C

Coefficient - a number that is connected to a variable by multiplication or division.

Commutative Property- (a)(b) = (b)(a)

Constant - a number that is not connected to a variable by multiplication or division.

D

Difference- subtraction

Distributive Property- a(b + c) = ab + ac

Domain - the set of all x values.

Dependent – the range or y-value for a function.

E

Expression- something you simplify and does not have an equals.

Equation- something you solve and has an equals.

Exponential Equation – y = abx

F

FOIL Method – a method used to multiply two binomials together “First, Outside, Inside, Last”

Function – a relation that for every x value there is only one y value.

G

Growth factor – the number b in an exponential function y = abx

I

Independent – the domain or x-value for a function.

Initial Value – the beginning value or the a value in an exponential function y = abx

L

Linear equation- an equation whose graph is a line.

Line of best fit- the trend line that shows the relationship between two sets of data.

M

Monomial – one term

Maximum – the highest point in a parabola that opens downward
