Answer:

Step-by-step explanation:
we know that
The equation of a exponential function is of the form

where
a is the initial value or y-intercept
b is the base of the exponential function
In this problem we have
----> the y-intercept is given
substitute

we have the other ordered pair (1,10)
substitute the value of x and the value of y and solve for b


substitute

see the attached figure to better understand the problem
Divide each side by 3. ----- n=M/3 .
I'm guessing 1 and 4, but I'm not sure.
