## 1.5A Polynomial Functions and Complex Zeros

Polynomial functions can have complex zeros when their solutions involve imaginary numbers. Complex zeros always occur in conjugate pairs if the polynomial has real coefficients. This means if a +

## 1.4 Polynomial Functions and Rates of Change

Polynomial functions represent relationships involving powers of the independent variable. The rate of change in polynomial functions can vary significantly depending on the degree and the coefficients of the polynomial.

## 1.3 Rates of Change in Linear and Quadratic Functions

The rate of change in linear and quadratic functions helps us understand how the output of these functions changes in relation to changes in their input values. Linear functions have

## 1.2 Rates of Change

A rate of change is a measure that describes how one quantity changes in relation to another quantity. In the context of functions, it often refers to how the output

## 1.1 Change in Tandem

A function is a specific type of relation between two sets, typically referred to as the domain (input values) and the range (output values). For each element in the domain,
