Question textSuppose [math: f(x,y)=y2−xy+3x+1]. (a) What is the maximum rate of increase of [math: f] at the point [math: (1,1)]? [input] Your last answer was interpreted as follows: 2.23606797749979This answer is invalid. Your answer contains floating point numbers, that are not allowed here. You need to type in numbers as fractions. For example, you should type 1/3 not 0.3333, which is after all only an approximation to one third.
