Students will be able to

• understand how a function is defined as well as what the domain, range, and roots of a function are,
• evaluate functions using substitution,
• find the roots of linear and quadratic (or quadratic-like) functions by solving them,
• find the input values for which two polynomial functions are equal,
• identify the minimum or maximum value of a quadratic function by finding its vertex form.
