Question

Will fan and give a medal if someone can check this and explain to me how i do it if i got it wrong:

A biologist took a count of the number of fish in a particular lake, and recounted the lake’s population of fish on each of the next six weeks.

Find a quadratic function that models the data as a function of x, the number of weeks. Use the model to estimate the number of fish at the lake on week 8.


P(x) = 13x^2 – 10x + 350; 917 fish (Its either this one)
P(x) = 13x^2 – 10x + 350; 1,102 fish (or this one)
P(x) = 18x^2 + 10x + 300; 1,252 fish
P(x) = 18x^2 + 10x + 300; 1,532 fish

Answer 1

well plug in x=8 and what do you get?

Answer 2

So it would be the second one?

Answer 3

Yes. I got that too
