Answer:
The Answer is D.
Step-by-step explanation:
To solve this question we should use the process of elimination.
We can clearly see that the function f(x) increases as x increases so we can rule out options A and C.
Now we have to decide between B and D.
So the format for a quadratic function is
The format for an exponential function is
So let's try exponential first:
at x = 0 we solve for a and b:
so we find b when x =5
b = 1.04060
Then we evaluate the value as x=10
As can be seen from both cases b is the same. This is a key chareteristic of an exponential function. So the Answer is D.
