7.5 ­ GRAPHING SQUARE/CUBE ROOT FUNCTIONS
INVERSE REMINDER:
What is the inverse of?
So, how could we find out what its graph looks like?
What about the graph of ?
GRAPHS OF RADICAL FUNCTIONS:
Have the form:
If a < 0, graph is reflected over x­axis.
If |a| > 1, graph is vertically stretched.
If |a| < 1, graph is vertically compressed.
Graph is shiftedh units horizontally and
k units vertically. DOMAIN AND RANGE:
• Square root graphs have restricted domains and ranges
that correspond to their h and k shifts
• There are NO restrictions on Cube root graphs, so their domain and range are both __________. .
