The graph below could be the graph of which exponential function?

The correct option is B.

Step-by-step explanation:

The general form of an exponential function is

Where, a is the initial value of the function and b is the growth factor.

If b>1, then f(x) is an increasing function and if b<1, then f(x) is an decreasing function

From the given graph it is noticed that the initial value of the function is 2. It means the value of a is 2.

The graph shows that the function is a decreasing function, therefore the value of b must be less than 1.

It means the required function is in the form of

Where, b<1.

In option B, b=0.5<1, therefore option B is correct.

c is the answer
