Question

By use of technology, we investigated Mary’s investment and created the model, M(x) = 3.03(1.28)2x, in thousands of dollars. What was Mary’s initial investment? $4.96 $3,030 $4,960 $3.03

Answer 1

Using an exponential function, it is found that Mary's initial investment was of $3,030.

What is an exponential function?

An exponential function is modeled by:

$y = ab^x$.

In which:

• a is the initial value.

• b is the rate of change.

Her investment model, in thousands of dollars, is:

$M(x) = 3.03(1.28)^{2x}$

Then a = 3.03, since we measure the amount in thousands of dollars, Mary's initial investment was of $3,030.
