The McBrides drove 317 miles on one day and 289 on the next day. What is the best estimate of the number of miles the McBrides drove in all during the two days?

Bplant 3 and 1 because if you look closely at the graph it will show how high it grew it was tricky but you'll get through with it

We know on the regular cosine graph, it decreases from 0 to pi. so, we need to set 0 as y.0 = 4 cos(2x-pi)0 = cos(2x-pi)2x-pi = pix = piwe already know the answer, but do pi on your own!
