Finding the Equation of a Tangent Line

In Exercises 25-32, (a) find an equation of the tangent line to the graph of f at the given point, (b) use a graphing utility to graph the function and its tangent line at the point and (c) use the derivative feature of a graphing utility to confirm your results.

26. f(x) = x^2 + 2x + 1 ... (-3, 4)
30. f(x) = sqrt(x - 1) ... (5, 2)
32. f(x) = 1/(x + 1) ... (0, 1)
