## Definitions

**Arithmetic Sequence**- A sequence made by__adding__the same value each time.**Geometric Sequence**- The same number is multiplied or divided by each element to get to the next.**Average Rate of Change**- Slope of the line through two points**Domain**- The set of all inputs (x values) of a function**Range**- The set of all outputs (y values) of a function**Explicit Formula**- A formula that allows direct computation for any term in a sequence.**Recursive Formula**- A formula that requires computation of all previous terms to find a value.**Exponential Function**- A function whose value is a constant raised to the power of the variable.**Term**- A value in a sequence - the first value in a sequence is the first time, the second value is the second term, and so on; a term is also any of the monomials that make up a polynomials.**Vertical Translation**- For every point, y has a different value by a constant.**Horizontal Translation**- For every point, x has a different value by a constant.**Linear Function**- A function with a constant rate of change and a straight line graph.**Exponential Function**- A function whose value is raised to the power of the variable.
