the graph of the function y = x2 is shown. how will the graph change if the equation is changed to y = 2x2?
a) the parabola will become wider.
b) the parabola will become narrower.
c) the parabola will move up 2 units.
d) the parabola will move down 2 units.

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.
