The graph below could be the graph of which exponential function

Step-by-step explanation:

Although the options of this question have not been given, but still we can find the function from its graph.

Let the function is,

This graph is passing through two points (0, 2) and (1, 1).

By substituting these points in the function we can find the values of a and b,

For (0, 2),

a = 2

For (1, 1),

Therefore, given graph represents an exponential function,

Or,  

your answer is #3 , 8 - 3 square root of 11
