The population of California was 10,586,223 in 1950 and 23,668,562 in 1980. Assume that the population grows exponentially.
(a) Find a function that models the population t years after 1950. (Round rate r to four decimal places.)
P(t) =

(b) Find the time required for the population to double. (Round your answer to the nearest whole number.)
yr after 1950

(c) Use the function from part (a) to predict the population of California in the year 2007. Look up California's actual population in 2007, and compare. (Round your answer to the nearest whole number.)

I did an exponential regression with your points with x=0 @1950.
y=10586223*1.0271826956707^x
