• Use Desmos and graph the derivative function f(x)=1/(x2+1). Then graph its antiderivative so that the maximum value of the antiderivative function is twice as great the maximum value of the functionf(x)=1/(x2+1)
• Using the graph of antiderivative function estimate the y-intercept and the end value of the function as (x-->+)
• Interpret the y-intercept and the end behavior of the antiderivative function off(x)=1/(x2+1)
