Answer:
all real numbers less than or equal to 3
Step-by-step explanation:
The range of the function is set of all y value for which the function is defined
To find out the range we look at the maximum or minimum point on the graph
Maximum point on the graph that is vertex is (-1,3)
x=-1 and y=3
The graph of y is below 3 (vertex)
So the range of the function is set of all real numbers less than or equal to 3
