Moore’s law states that the number of transistors per integrated circuit, which indicates the processing power of a computer, doubles every year. The graph below shows information about the processing power of a computer by year. Which equation below shows the processing power of a computer by year, where y is the number of transistors and x is the number of years since 1966?
A. y=2^x
B. y=2(60)^x
C. y=60(2)^-x
D. y=60(2)^x
