Author: Hector Soto
##### Description:
• Use units as a way to understand problems and to guide the solution of multi-step problems; choose and interpret units consistently in formulas; choose and interpret the scale and the origin in graphs and data displays.
• Reason quantitatively and use units to solve problems.
• Understand that a function from one set (called the domain) to another set (called the range) assigns to each element of the domain exactly one element of the range. If f is a function and x is an element of its domain, then f(x) denotes the output of f corresponding to the input x. The graph of f is the graph of the equation y = f(x).
• Use function notation, evaluate functions for inputs in their domains, and interpret statements that use function notation in terms of a context.
• Relate the domain of a function to its graph and, where applicable, to the quantitative relationship it describes.
