Sketch the Graph of Functions

Sketch the Graph of Functions

Postby nycmath » Wed Sep 02, 2026 6:31 pm

Precalculus
Michael Sullivan
Edition 10
Chapter 2, Section 2.4

My steps for graphing basic functions by hand are as follows:

A. Make a table for points.
B. Select 3 values for x to find f(x).
C. Plot all three points on the xy-plane.
4. Connect each point with a straight line or curve, depending on the given function.

Note: If you have a better way to do this, please share.

You state the domain and range but do not explain how to obtain the information.

Nice picture. By the way, you can use Desmos for graphs unless the question specifically tells you otherwise.
