WebNov 10, 2024 · A function of two variables z = f(x, y) maps each ordered pair (x, y) in a subset D of the real plane R2 to a unique real number z. The set D is called the domain of the function. The range of f is the set of all real numbers z that has at least one ordered pair (x, y) ∈ D such that f(x, y) = z as shown in Figure 14.1.1. WebQuestion: Consider \( f(x, y)=x y+1 / x+2 / y \). (a) Find and sketch the domain of \( f \). (b) Find the local minima, local maxima, and saddle points of \( f \). Show transcribed image text. Expert Answer. Who are the experts?

The Derivative Calculator supports solving first, second...., fourth derivatives, as well as implicit differentiation and finding the zeros/roots. You can also get a better visual and understanding of the function by using our graphing tool.
WebConsider f(xy)-f(x). Differentiating with respect to x yields yf'(xy)-f'(x)=\frac{y}{xy}-\frac{1}{x}=0, meaning that f(xy)-f(x)=C, where C is a constant.
WebFind the inverse of f (x) = 2x + 1 Let y = f (x), therefore y = 2x + 1 swap the x"s and y"s: x = 2y + 1 Make y the subject of the formula: 2y = x - 1, so y = ½ (x - 1) Therefore f -1 (x) = ½ (x - 1) f -1 (x) is the standard notation for the inverse of f (x). chocolate brown poopWebShare a link to this widget: More.
