If $7500 is invested at an interest rate of 5% each year, what is the value of the investment in 4 years? write an exponential function and solve.
a. y = 4 (1.05) superscript 7500;$7859.91
b. y = 7500 (4) superscript 1.05;$32,153.20
c. y = 7500 (1.05) superscript 4;$9116.30
d. y = 7500 (1.05) superscript negative 4;$6170.27
