Given:
The graph of a function.
To find:
The range of the function.
Solution:
Domain is the set of input values for which the function is defined.
Range is the set of output values or y-values.
From the given graph it is clear that the function is defined between -2 and 1.
The graph of the function is a horizontal line and it gives the value 1 for each input between -2 and 1.
It means the range of the graphed function is 1.
Therefore, the correct option is C.
