Title: 2_2 Graphs of Functions and Parametric Form
Course: HELM Workbooks 2023-2024 > Section: HELM 2: Basic Functions

Mathematical ideas are often easier to understand when they are portrayed visually as opposed to algebraically. Graphs are a convenient and widely-used way of portraying functions. By inspecting a graph it is easy to describe a number of properties of a function. For example, where is the function positive, and where is it negative? Where is it increasing and where is it decreasing? Do function values repeat? Questions like these can be answered once the graph of a function has been drawn. In this Quiz, we will describe how the graph of a function is obtained and introduce various terminology associated with graphs.
