Question

Part D: What is the value of Mikayla's scooter after 4 years?

Answer 1

Answer:

-The function models exponential growth.

-200 represents the amount of money Jordan put in his savings account in the beginning.

Step-by-step explanation:

-An exponential growth can be of the form :

$y = ab^x, b=(1+r)$

Where y is the quantity after time x, r is the rate of growth and a is the initial quantity.

-Given the function $f(x)=200(1.02)^x$

The rate of growth is 2% and the initial amount is $200.

The amount after 1 and 4 months are:

$f(1)=200(1.02)^1=204.00\\\\f(4)=200(1.02)^4=216.49$

Hence, the only correct option is:

• The function models exponential growth.
• 200 represents the amount of money Jordan put in his savings account in the beginning.
