Question 1:

. Use partial derivatives to locate critical points for a function of two variables. Find the critical point of the function: f(x, y) = 2 - 6x + x2 - 7y - y2 (x, y)= Select an answer Saddle This critical point is a: v Minimum Maximum Question Help: Vidu0 Use partial derivatives to locate critical points for a function of two variables. Find the values of m, y and z that correspond to the critical point of the function: f(:c, y) = 2:62 4m 73; + 5y2 Enter your answer as a number (like 5, -3, 2.2) or as a calculation (like 5/3, 2'3, 5+4). - Use partial derivatives to locate critical points for a function of two variables. Find the points on the cone 22 = m2 + y2 that are closest to the point (4, -4, 0). Please show your answers to at least 4 decimal places
