Suppose HH is an antiderivative of h(x)=2x+1x2+xh(x)=\dfrac{2x+1}{x^{2}+x} defined for all x>−1x>-1. You are told that H(0)=3H(0)=3 and that H(1)=2H(1)=2. (a) Compute the most general form of H(x)H(x) by evaluating ∫h(x) dx\int h(x)\,dx. Show each step of your integration, including algebraic manipulation where needed. (b) Use the condition H(0)=3H(0)=3 to determine the value of the integration constant, and write the resulting particular antiderivative. (c) Evaluate your result from part (b) at x=1x=1. Compare the computed value with the second given condition H(1)=2H(1)=2, and state whether the two conditions are simultaneously consistent. (d) Provide a clear mathematical justification for your conclusion in part (c). If the conditions are inconsistent, explain precisely why no single antiderivative of hh can satisfy both points; if they are consistent, confirm that your antiderivative meets both conditions.
