Question

What is the range of this function?

Answer 1

The range is a set of elements from the second set.

Therefore your answer is:

D. { -4, 1, 7, 15 }

Answer 2

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}
