Bruno was given $2000 at birth . His parents invested it at a 2% interest rate compounded bi-annually. No deposits or withdrawls were made. Which expression can be used to determine how much money Bruno had in the account when he turned 13?

Answer explanation

Which of the following represents an exponential function?

• y = 2x + 8

• y = 5√x - 9

• y = -3^x - 8

• y = (x + 6)² - 9

What must be true for "a" and "b" for this to represent an exponential growth?

• a≠0, and 0<b<1

• a>0, and b>1

• 0<a<1, and b ≠ 0

• a>0, and b ≠ 0
