Answer:
r(x)=0.0875(1.99430199)^x
Step-by-step 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
