### Outcomes

#### A.REI.D.10

Understand that the graph of an equation in two variables is the set of all its solutions plotted in the coordinate plane, often forming a curve (which could be a line).

#### F.IF.B.4'

For a function that models a relationship between two quantities, interpret key features of graphs and tables in terms of the quantities, and sketch graphs showing key features given a verbal description of the relationship. Key features include: intercepts; intervals where the function is increasing, decreasing, positive, or negative; relative maximums and minimums; symmetries; end behavior; and periodicity. 'Linear and exponential, (linear domain)

#### F.IF.B.5'

Relate the domain of a function to its graph and, where applicable, to the quantitative relationship it describes. 'Linear and exponential, (linear domain)
