In a chemistry class, the students in a lab derived a function to model the results of their experiment on the effect of heat on a chemical where x represents the number of minutes heat was applied at a constant temperature set by the lab instructions. Their function was f(x)=x2+216x​. The teacher said the function should have been f(x)=x2+112x​. a. Was there ever any time at which these two functions were the same. If so, when? [A3] b. For what values of x is their derived function greater than the actual function? [A3] c. Why would you not consider any x<0 when looking for your answer to part b? [A1]
