How do you find the maximum value of X and Y?

Short method: If sum of two variables is a constant, then the product of both numbers will be maximum when both the numbers are equal. product of x and y will be maximum when x = y = 6/2 = 3.

What is the maximum value of x 3y 3 3x y when x y 8?

The maximum possible value is 4144. Originally Answered: What is the maximum value of x3y3 + 3 x*y when x+y = 8?

What is the minimum value of x y?

Hence, minimum value for xy should be 0. Logically, if you take x and y as both positive, then xy will be positive. However, if you take y to be negative, then xy will be negative.

What is saddle point Mcq?

Explanation: Saddle point is a point where function have neither maximum nor minimum value. Explanation: Point where function f(x,y) either have maximum or minimum value is called saddle point.

How do you find the maximum and minimum value?

Finding max/min: There are two ways to find the absolute maximum/minimum value for f(x) = ax2 + bx + c: Put the quadratic in standard form f(x) = a(x − h)2 + k, and the absolute maximum/minimum value is k and it occurs at x = h. If a > 0, then the parabola opens up, and it is a minimum functional value of f.

What is the formula of maximum?

The Excel MAX Formula is used to find out the maximum value from a given set of data/ array. MAX function in Excel returns the highest value from a given set of numeric values. Excel MAX formula will count numbers but ignore empty cells, text, the logical values TRUE and FALSE, and text values.

How do you find a saddle point?

If D>0 and fxx(a,b)<0 f x x ( a , b ) < 0 then there is a relative maximum at (a,b) . If D<0 then the point (a,b) is a saddle point. If D=0 then the point (a,b) may be a relative minimum, relative maximum or a saddle point. Other techniques would need to be used to classify the critical point.
