Answer:
f(x) = 8·1.25^x
Step-by-step explanation:
An exponential function has the form ...
... f(x) = a·b^x
Then f(0) = a. Your graph shows f(0) = 8.
The base "b" can be found from any other point on the graph. You have marked the point (1, 10), so we can find "b" from ...
... f(1) = 10 = 8·b^1 = 8b
... 10/8 = b = 1.25 . . . . . . . divide by the coeffiicient of b
Now, we know the exponential function is ...
... f(x) = 8·1.25^x
