(calculus) please help!! Find the values of x for all points on the graph of
f(x)=(x^3)-(2x^2)+5x-16
at which the slope of the tangent line is 4

Pick the description of a geometric object that best matches the real world object box for a deck of card

What is 32+4 x (16 x 1/2) -2 show your work}

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
