Answer:No, this does not represent an exponential function because his savings does not increase by a constant ratio.

Answer:

it does not

this is because his income increases at a constant rate. At any given week, his income increases by double

Explanation:

An exponential function is usually in the form :
a^(x)

where a = positive constant other than 1

x = variable component

for example ,

Assume that Jordan saves $15. he increases this amount by 10% weekly. this statement represents an exponential function.

The amount he would have in 7 weeks = 15 x (1.1)^7 = 29.23
