Unit 3: Linear and Exponential Functions

4. A formula that requires the computation of all previous terms to find the value of an.
5. If x is the independent variable and y is the dependent variable, then this term is f(x), read “f of x”, where f names the function.
7. The set of all possible outputs of a function.
9. Change The change in the y-value divided by the change in the x-value for two distinct points on the graph.
11. the domain of the function where its values get larger.
13. The set of x-coordinates of the set of points on a graph; the set of x-coordinates of a given set of ordered pairs. The value that is the input in a function or relation.
14. A nonlinear function in which the independent value is an exponent in the function, as in y = ab^x .
15. A formula that allows direct computation of any term for a sequence a_1,a_2,a_3,...,a_n,....
18. The appearance of a graph as it is followed farther and farther in either direction.

1. a special relationship where each input has a single output.
2. A sequence of numbers in which the difference between any two consecutive terms is the same.
3. A function with a constant rate of change and a straight line graph.
6. A shift in which a plane figure moves vertically.
8. the domain of the function where its values get smaller.
10. A sequence of numbers in which the ratio between any two consecutive terms is the same.
12. A notation representing an interval as a pair of numbers. The numbers are the endpoints of the interval.
16. The independent variable or variables in a system of equations with more than one dependent variable.
17. A value in a sequence
