Which of the following is not a way to represent the solution of the inequality 2(x − 2) less than or equal to 2? a number line with a closed circle on 3 and shading to the right a number line with a closed circle on 3 and shading to the left 3 greater than or equal to x x less than or equal to 3

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
