The graph of f(x) is given below. Select each true statement about the continuity of f(x) at x = 1.
Select all that apply:
☐ f(x) is not continuous at x = 1 because it is not defined at x = 1.
☐ f(x) is not continuous at x = 1 because lim f(x) does not exist.
x+1
☐ f(x) is not continuous at x = 1 because lim f(x) ‡ f(1).

A homeware company has been approached to manufacture a cake tin in the shape
of a "ghost" from the Pac-Man video game to celebrate the 45th Anniversary of the
games launch. The base of the cake tin has a characteristic dimension / and is
illustrated in Figure 1 below, you should assume the top and bottom of the shape
can be represented by semi-circles. The vertical sides of the cake tin have a height of
h. As the company's resident mathematician, you need to find the values of r and h
that minimise the internal surface area of the cake tin given that the volume of the
tin is Vfixed-
2r
Figure 1 - Plan view of the "ghost" cake tin base.
(a) Show that the Volume (V) of the cake tin as a function of r and his
2(+1)²h
V = 2
