Let L(c) be the length of the parabola f(x)=x² from x = 0 to x=c, where c20 is a constant. a. Find an expression for L and graph the function. b. Is L concave up or concave down on [0,00)? c. Show that as c becomes large and positive, the arc length function increases as c²; that is L(c) kc², where k is a constant.
