The cosecant is the reciprocal of the sine. - Evaluating functions - Domain range of functions - Graphical features of functions - Average rate of change of functions - Function combination and composition - Function transformations shift reflect stretch - Piecewise functions - Inverse functions - Two-variable functions.
We can graph in the coordinate plane when we have 1 input to 1 output. If we have a function with 2 inputs to create 1 output we can graph in a 3 dimensional graph of x y z. The graph of a polynomial function is a smooth curve that may or may not change direction depending on its degree.
This chapter is about functions this is how we express relationships between quantities and their graphs.
The quadratic y x2 is one of the two simplest polynomials. F x x. Rational Function A rational function is a function of the form r x P x Q x where P and Q are polynomials. Decompose a composite function.
