Then find the area s of the region.

y=2 x^2, y^2=1/2 x

Recall that the area under a curve and above the x axis can be computed by the definite integral.  If we have two curves

        y = f(x) and y = g(x)

such that 

        f(x) > g(x) 

then the area between them bounded by the horizontal lines x = a and x = b is

To remember this formula we write

question: how many people can she serve?

answer: she can serve 16.66666667 people. so she can only give 16 people a complete serving.

question: does she have enough ice cream for her guests?

answer: no. explanation: she only has enough for 16 people to have a full serving. however, she can give a 17th person a partial serving.
