4) For the function p = x2y+ yz at the point (1,2,-1), find its rate of change with distance in the direction d = i + 2j + 3k. At this same point, what is the greatest possible rate of change with distance and in which direction does it occur? %3D V. (ỹ × 6)

Mr. Goza rode his bike towards Santa Barbara. We don't have any data for his velocity during the first 2 hours but P,(2) = 22. The velocity data we were able to collect is shown below. 10 hours -10- miles/hour
