Question

Plz plz help!
The table contains some points on the graph of an exponential function.

Answer 1

r(x)=0.0875(1.99430199)^x

Explanation:

When x=0, y is going to equal the y-intercept, so when x=0 y(or in this case r(x)) =0.0875, so that's going to be your A

a-0.0875

To find the rate, divide a lower number by a higher one to find the rate: 0.175/0.0875=1.99430199

1.99430199 is the constant rate.

r(x)=a(b)^x this is the formula

substitute:

r(x)=0.0875(1.99430199)^x
