Which table shows a proportional relationship between x and y?

a: x 2 3 4 5
y 7 9 11 13

b: x 3 6 8 10
y 12 15 18 20

c: x 1 2 7 8
y 0.5 1 3.5 4

d: x 3 7.5 15 20
y 1 2.5 4 6

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
