Sketch a possible graph of a continuous function f that has domain [0,3], where f(0)=-3 and the graph of y=f'(x) is shown. Thank you so much for the help. It is making the concepts far more clear.

What is an equation of the line tangent to the graph of f(x)=x2(2x+1)3 at the point where x=-1? (that's x squared (2x+1)cubed) I'm having trouble finding the derivative:f'(x)which would be the slope (m).

slope of AB = 3/4 slope of CD = 3/4 slope of BC = -4/3 slope of DA = -4/3 sides are parallel and perpendicular in pairs, so it's a rectangle |AB|=|CD| = 5 |BC|=|DA| = 5 sides are all equal lengths, so it's a square.

Triangle ABC, A at the top, B & C at the bottom, B left & C right. The length of a triangle median is defined by (Ma)^2 = (b^2 + c^2)/2 - a^2/4. (Ma is the median from vertex A to side "a".) (Mb)^2 = (a^2 + c^2)/2 - b^2/4 (Mc)^2 = (a^2 + b^2)/2 - c^2/4 ...
