Question

By inspecting a graph of y = sin x, determine whether the function y = sin x is increasing or decreasing on the interval The function y=sin x is on the interval By inspecting a graph of y = sin x, determine whether the graph is concave up or concave down on the interval (1,21). The graph is on the interval (1,21). Minimize f(x,y)= x2 + xy + y2 subject to y = 20 without using the method of Lagrange multipliers; instead, solve the constraint for x or y and substitute into f(x,y). Use the constraint to rewrite f(x,y) = x2 + xy + y2 as a function of one variable, g(x). g(x) = The minimum value of f(x,y) = x2 + xy + y2 subject to y = 20 occurs at the point (Type an ordered pair.) The minimum value of f(x,y) = x2 + xy + y2 subject to y = 20 is (Simplify your answer.) Graph the region R bounded by the graphs of the given equations. Use set notation and double inequalities to describe R as a regular y region. y2 = 2x, y=x-40 Choose the correct graph of the region R below.
