Facts to Know:
Graphs of Basic Functions:
Plotting Points:
Graph Transformations: If we have a graph of f(x), obtain transformed graphs by
• f(x) + c:
• f(x+ c):
• cf(x):
• f(cx):
Inverse Functions:
Examples:
1. Graph the function 2x2 � 1.
-
2. Graph the function sin(⇡x).
3. Using the graph of tan(x), graph arctan(x) = tan�1(x).
