Which equation is quadratic in form? 2(x + 5)^2 + 8x + 5 + 6 = 0 x^6 + 6x^4 + 8 = 0 7x^6 + 36x^3 + 5 = 0 4x^9 + 20x^3 + 25 = 0

To find the extreme values of a function f(x.y) on a curve x-x(t), y y(t), treat f as a function of the single variable t and use the chain rule to find where df/dt is zero. in any other single-variable case, the extreme values of f are then found among the values at the critical points (points where df/dt is zero or fails to exist), and endpoints of the parameter domain. find the absolute maximum and minimum values of the following function on the given curves. use the parametric equations x=2cos t, y 2 sin t functions: curves: i) the semicircle x4,y20 i) the quarter circle x2+y-4, x20, y20 b, g(x,y)=xy
