Me its already late and its bringin my grade way down hepl
the following graph is of an exponential function of the form y=a*bx.
what values of a and b would make this equation work?
a=
b=

Step-by-step explanation:

we have an exponential function of the form

where

a is the initial value or y-intercept

b is the base

Looking at the graph

we can see the ordered pairs (0,15) and (1,5)

(0,15) ---> y-intercept

so

The value of a is equal to

substitute

with the point (1,5) find the value of b

For x=1, y=5

substitute in the exponential function

solve for b

therefore

The exponential function is

answer: the common difference is -0.10
