Explain why the graph of the function f(x) = (x2 + 1) ln(1/2x) lies
below the x-axis for 1 < x < 2 and above the x-axis for 2 < x < 3.
The graph of the function f(x)=(x^2+1) ln(1/2x) is positive above the x-axis and negative below the x-axis.
Use this fact to find the area enclosed by the graph and the x-axis
between x = 1 and x = 3, giving your answer to five decimal
Can anyone help me.
