Which of the relations are functions? O A. Only Relation T is a function.
OB. Only Relation S is a function.
O C. Relations S and T are both functions.
OD. Neither Relation S nor Relation T is a function.

Describe the possible echelon forms of the standard matrix for a linear transformation t where t: set of real numbers is onto.

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
