I need help with the following questions please.

Suppose the marginal cost is C'(X) = 0.24x2 26.4x + 741 to produce x items. Complete parts a through c. (a) Use a graph or a table on a calculator to nd the coordinates of the vertex of C'(x). The vertex is . (Type an ordered pair.) (b) What do the coordinates represent in terms of production costs? The cost to increase production from to units is approximately dollars. 5 (c) Find rCTX) dx and interpret what the quantity means. 55 5 JECTX) dx= Y 55 5 JEC'OQ dx is the additional cost if the company increases production from to units. 55 Find the area of the region bounded by the graphs of the given equations. y= x+2, y=x2 The area is (Type an integer or a simplified fraction.)
