Graph the data in the table below. Which kind of function best models the data? Write an equation to model the data.
quadratic; y = –x2 + 2x – 3
linear; y = – 2x – 3
exponential; y = –3•1.5x
quadratic; y = –x2 – 3

Best ResponseYou've already chosen the best response.1ok let's say we pick on choice B linear; y = – 2x – 3

Best ResponseYou've already chosen the best response.1IF the answer was choice B, then (0,3) should lie on the graph so should (1,2) and (2,3) etc etc

Best ResponseYou've already chosen the best response.1but what is the value of y when x = 1 y = – 2x – 3 y = 2*1  3 y = ??

Best ResponseYou've already chosen the best response.1yes so (1,5) is actually on y = – 2x – 3 not (1,2)

Best ResponseYou've already chosen the best response.1well you could, but we proved B wasn't the answer. So there's no need to check B any more
