The graph below could be the graph of which exponential function?
A. F(x) = 3. (0.4)^x
B. F(x) = 3 • (-1.4)^x
C. F(x) = 3: (1.4)^x
D. F(X) = 3^x

C. F(x)=2 * (0.7)^x.

Step-by-step explanation:

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.

final total: 63
