Question

Jordan has saved $15. He doubles the amount he saves each week. Does this represent an exponential function? Why?

Answer 1

Answer:

it does not

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

Step-by-step 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
