What is the range of the function on the graph

Answer:
All the real numbers greater or equal to -3.
Step-by-step explanation:
The range is the set of all possible resulting values of a function. The graph of a function [tex]f(x)[/tex] shows us the points [tex] (x, f(x))[/tex] on the plane, the x-coordinate is the value and the y-coordinate is the function evaluated at the original value. In our case all the points on the graph have y-coordinate bigger or equal to -3.
