Answer: {-4,1,7.15}
Step-by-step explanation:
The range of a function is the set of all output values .
In the given diagram , it can be seen that all the values in domain {-1,4,8,18}(from where the arrow start) is mapping to all the values of the codomain {-4,1,7,15} ( where the arrow ends).
Thus, here Range = Codomain ={-4,1,7,15}
Hence, the range of this function : {-4,1,7,15}
