Gordon Moore stated that the number of transistors that can be placed on an integrated circuit will double every 2 years. This trend is known as Moore's Law. In 1978, the Intel 8086 held 29,000 transistors on an integrated circuit.

a. Write a function that represents Moore's Law, where t is the number of years since 1978.

b. How many transistors could be placed on an integrated circuit in 2015?
