The patterns for graphing square root functions apply to other radical functions.
Problem 5 Graphing a Cube Root Function
What is the graph of
Plan
How is
a stretches or shrinks the parent function and h and k translate it horizontally and vertically.
-
Step 1 Graph the parent function,
-
Step 2 Multiply the y-coordinates by 2.
This stretches the graph vertically.
- Step 3 Translate the graph from step 2, 1 unit to the left and 4 units down.
