Applications of equations

Wordy word problems which are wrought with words

Quiz on Wednesday over the following standard

CCSS: Mathematics, CCSS: HS: Functions, Interpreting Functions

HSF-IF.A. Understand the concept of a function and use function notation.

HSF-IF.A.1. 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).

Quiz on Wednesday over the following exercise type
