To graph the integral of f(x) = x, first calculate the integral, which is ∫x dx = (x²/2) + C, where C represents the constant of integration. This results in a family of parabolas, each corresponding to different values of C. The process involves finding the integral and then plotting the resulting function. Each graph will vary based on the chosen constant, illustrating the concept of a family of curves. Understanding this process is essential for accurately graphing integrals.
