g(x)=1/2x

a) obtain

b) obtain y

c)Locate in a plane a (, ). It involves graphing both functions.

and : coordinates of the centroid of a figure

To consider: Use the roots of Exercise 2 for the limits of integration. Remember that to calculate there is a difference of squares in the numerator -the subtracted functions squared each-.
