The processing power of a computer is essentially how quickly the computer can perform tasks and calculations. The higher the number of transistors in an integrated circuit, the more processing power that computer has. In 1975, Gordon Moore predicted that the number of transistors in a dense integrated circuit doubles every two years. So far, the so-called ``Moore's Law" has proven to be accurate.

a) If there were 2925 transistors in an integrated circuit in 1971, write a formula for the number of transistors as a function of years since 1971.

b) About how much (as a percentage) does computing power increase each year?
