Answer:

y=5^{2} +2

Step-by-step explanation:

A function f from a set A to a set B is a relation that assigns to each element x in the set A exactly one element y in the set B. The set A is the domain (also called the set of inputs) of the function and the set B contains the range (also called the set of outputs).

To solve this problem, we have plotted each function and are shown in order below. As you can see:

y=2^{x}

y=2(5^{2} ) and y=5^{x+2}

have the same range (0,∞). The only graph that shows a range (2,+∞) is the function y=5^{x} +2 so that's the answer.
