Examples for

Common Core Math: High School Functions: Interpreting Functions

In high school, students study linear, quadratic, polynomial, exponential, logarithmic, rational and trigonometric functions. These functions can be represented with equations, words, graphs, diagrams, sequences or tables. Each time students discover a new type of function, students learn to perform relevant computations for locating key features such as x-intercepts (also called "roots" or "zeros"), y-intercepts, maxima and minima, end behavior, discontinuities, monotonicity, periodicity and more.
