Here is the pic if u can help me

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.

Rewrite the equation x = 65 - 60p by factoring the side that contains the variable p.

How many and of which kind of roots does the equation f(x)=2x^4−9x^3+17x^2−16x+6 have?
