Find an exponential function of the form Upper P left parenthesis t right parenthesis equals Upper P 0 n Superscript StartFraction t Over Upper T EndFraction that models the situation, and then find the equivalent exponential model of the form Upper P left parenthesis t right parenthesis equals Upper P 0 e Superscript rt. Doubling time of 5 yr, initial population of 350. Question content area bottom Part 1 Find an exponential function of the form Upper P left parenthesis t right parenthesis equals Upper P 0 n Superscript StartFraction t Over Upper T EndFraction that models the situation. The exponential function is P(t)equals enter your response here. (Use integers or fractions for any numbers in the expression.) Part 2 Find the equivalent exponential model of the form Upper P left parenthesis t right parenthesis equals Upper P 0 e Superscript rt. The exponential model is P(t)equalsnothing e Superscript nothing t . (Round to four decimal places as needed.)
