Terms You Need To Know
1.Function- a relation in which the x-value is paired with only one y-value
ex. f(x)= 9x + 8
2. Linear Function - a function with a constant rate of change and a straight line graph
ex. f(x)= 9x + 8
2. Linear Function - a function with a constant rate of change and a straight line graph
3. Exponential Function- a nonlinear function that changes at a constant ratio and has a curve line graph
4. Arithmetic Sequence- A sequence of numbers in which the common difference is added to get the next term
ex. 10, 20, 30 ,40 ,50, 60, 70
5. Geometric Sequence- A sequence of numbers in which the ratio is the same between any two consecutive numbers and you multiply by the same common ratio to get the next term
ex. 10, 100, 1000, 10000
6.Domain- The set of x-coordinates of the given points on a graph and in ordered pairs.
ex. x- 2, 4, 6, 8, 10 y- 1, 2, 3 ,4 ,5
7. Range - The set of y- coordinates of the given points on a graph and in ordered pairs
ex. y- 1, 2, 3 ,4 ,5 x- 2, 4, 6, 8, 10
8. Recursive Formula- Is a formula that is used to determine the next term in a sequence using one or more of the previous terms.
ex. Sequence: 3, 9, 27, 81
a1= 3
an= 3an-1
9. Explicit Formula - Is a formula that is used to determine any term in a sequence
ex. Sequence: 2, 4, 8, 16, 32
an= 2^n
10. Term - A value in a sequence
ex. 9, 18, 36, 54, 108 ( 18 is a value in the given sequence)
ex. 10, 20, 30 ,40 ,50, 60, 70
