DIRECTIONS: Using the Four Principal Rays explained in page 9, analyze and locate the image formed in curved mirrors. The first one is done for you (3 points each). (construct ray diagrams to determine the, Location, Orientation, Size, and Type of images formed by curved mirror)

Is there a direction u in which the rate of change of f(x,y)equals=x squared minus 3 xy plus 4 y squaredx2−3xy+4y2 at p(1,2) equals 14? give reasons for your answer. choose the correct answer below. a. no. the given rate of change is smaller than the minimum rate of change. b. no. the given rate of change is larger than the maximum rate of change. c. yes. the given rate of change is larger than the minimum rate of change and smaller than the maximum rate of change.
