I need help on this question

Application of Difference Quotient In the function P(t) = 309.3 . 1.005, P represents the population in millions and t represents the number of years since 2010. Find the population in 2017 and the rate at which the population is growing in 2017. Use h = 0.001 to estimate the derivative with the difference quotient. The population in 2017 is million. The rate at which the population is growing in 2017 is million people per year. ( Keep ALL decimal places on both parts. ) Hint: The population in 2017 is P(7). The rate of change in 2017 is P'(7)
