# Common Core Math: High School Functions

Functions are tools that mathematicians use to describe and make predictions about mathematical relationships. In high school, students formalize the definition of a function in terms of domain and range and are introduced to various new types of functions including linear, quadratic, polynomial, rational, exponential, logarithmic and trigonometric functions. Students learn to represent and transform functions using equations, graphs and numerical methods. Students analyze and compare the behavior of different types of functions, noting function properties such as growth rates, intercept values, symmetries, asymptotes, discontinuities and periodicity.
