Question

Which of the following functions shows an original investment of $200?

a. y=200(1.02)^x
b. y=5(200)^x
c. y=3(x)^200
d. y=2000(0.5)^x

Answer 1

A shows an original investment of $200

Explanation:

If you plug in x=0, you will get the value of the original investment

When you plug x=0 into A you get

`y=200(1.02)^(0)`

This simplifies to

`y=200(1)`

And finally to

`y=200`
