For two functions, m(x) and p(x), a statement is made that m(x) = p(x) at x = 7. what is definitely true about x = 7?
both m(x) and p(x) cross the x-axis at 7
oth m(x) and p(x) cross the y-axis at 7
both m(x) and p(x) have the same output value at x = 7
both m(x) and p(x) have a maximum or minimum value at x = 7.

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
