- The tuition in the school year 2012–2013 at a certain university was $15,000. For the school year 2017–2018, the tuition was $17,850. Find an exponential growth function for tuition T (in dollars) at this university t years after the 2012–2013 school year. (Round your values to four decimal places.) T = Assuming it increases at the same annual rate, use the function to predict the tuition (in dollars) in the 2021–2022 school year. (Round your answer to the nearest integer.) $arrow_forwardExer. 31-32: Find an exponential function of the form f(x) = ba-* + c that has the given horizontal asymptote and y-intercept and passes through point P. 31 y = 32; y-intercept 212; P(2, 112) 32 y = 72; y-intercept 425; P(1, 248.5)arrow_forwardmodel a population p if its rate of growth is proportional to the amount present at time tarrow_forward
