Question

9. How does the function y = 2x compare to the function y = (?)". Include at least three comparisons for credit. (3 points)

Answer 1

11.

a.

$y=5000(0.98)^x$

The y-intercept is given by:

$\begin{gathered} y(0)=5000(0.98)^0 \\ y(0)=5000(1) \\ y(0)=5000 \end{gathered}$

The y-intercept is:

$(5000,0)$

The y-intercept represents the initial amount of money in the inactive account

b.

$1-0.98=0.02$

The decay rate is 0.02 or 2% it means that each year the amount of money in the account is decreased by 2%
