Photo necessities produces camera cases. they have found that the cost, c(x), of making x camera cases is a quadratic function in terms of x the company also discovered that it costs $28 to produce 2 camera cases, $50 to produce 4 camera cases, and $140 to produce to camera cases. find the total cost of producing 12 camera cases

A graphing calculator can do quadratic regression on the given points. It tells you the cost function is
.. c(x) = (1/2)x^2 +8x +10

Then c(12) = 178

The cost function predicts the total cost of producing 12 camera cases is $178.

In all honesty, there really is no “work” per say to show. mainly it’s just using the process of elimination. the question is asking which domain(s) would be the most appropriate for the function c(n). n is the number of observed vehicles so right away, 1, 2, and 3 can be eliminated.why? 1, 2 start in the negatives and therefore it is impossible to observe negative cars. so, #4 would be the best answer to the given problem.
