The exponential function is given in the form

where a is the initial value and b is the multiplicative rate of change
So lets plug the first two values of the table in this function , we get
or

Now plug second

Divide equation 2 by equation 1

On simplifying we get

or

So the multiplicative rate of change of the function is

The answer would be 3.1428
(6•x) + 7 = 8
6x + 7 = 8
6x = 1
X = 1
8. 6m + 3n
11. 8r^3 - r^2
12. 3h^2 + 8
hope this helps !
F(x) = 2x + 3 i think would be the best way to write it
