### Examples

*Algebra 1 Example:*The value of a classic car produced in 1972 can be modeled by the function , where

*t*is the number of years since 1972. In what year does the car’s value start to increase?

### Clarifications

*Clarification 1*: Key features are limited to domain; range; intercepts; intervals where the function is increasing, decreasing, positive or negative; end behavior; vertex; and symmetry.

*Clarification 2*: Instruction includes the use of standard form, factored form and vertex form.

*Clarification 3*: Instruction includes representing the domain, range and constraints with inequality notation, interval notation or set-builder notation.

*Clarification 4*: Within the Algebra 1 course, notations for domain, range and constraints are limited to inequality and set-builder.
