Use the model from problem 12 to estimate the population of bacteria at 9 hours. type your answer below. show your work.

Check the picture below.

that's done just with the provided links, and I simply ran a line, so it'll be thereabouts, roughly between 13 and 14, depending on how you hang the line.

anyhow, if you have a TI(texas instruments) 89+ or higher, you can just provide the value pairs of the data and run a quadratic regression, or an exponential.

there are some online regression calculators as well.

Ithink it's the first one ( let me know if it right)
