For a function that models a relationship between two quantities:
i) interpret key features of graphs and tables in terms of the quantities; and
ii) sketch graphs showing key features given a verbal description of the relationship.
Key features include the following: intercepts; zeros; intervals where the function is increasing, decreasing, positive, or negative; maxima, minima; and symmetries.  Tasks have a real-world context and are limited to the following functions: linear, quadratic, square root, piece-wise defined (including step and absolute value), and exponential functions of the form f(x)=a(b)x where a>0 and b>0 (b≠1).

For a function that models a relationship between two quantities:
i) interpret key features of graphs and tables in terms of the quantities, and
ii) sketch graphs showing key features given a verbal description of the relationship.
Key features include: intercepts, zeros; intervals where the function is increasing, decreasing, positive, or negative; relative maximums and minimums; symmetries; end behavior; and periodicity.  Tasks may involve real-world context and may include polynomial, square root, cube root, exponential, logarithmic, and trigonometric functions.
