Question 13 of 36 If f is the unknown number of fruit slices, which equation best represents the situation described below? Hampton ate 7 slices of fruit at lunch. After dinner, he ate some more. He ate a total of 15 slices of fruit. A. 4-15 B. 714 15 C. 7-f-15 D. 7 +5 - 15​

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.
