STEP - BY - STEP EXPLANATION
What to find?
The domain.
The range.
Given:
Domain:
Sets of x - values for which the graph is defined and real.
Hence, domain of the graph is [-18, 18]
Range :
Sets of y - values for which the function is defined and real.
Hence, range is [ - 8, 12]
ANSWER
Domain : [-18, 18]
Range : [ - 8, 12]
