1. In exercises 25 to 32, a) find the equation of the tangent line to the graph of f at the indicated point, b) use a computer to draw the graph, the function and its tangent line at said point, and c) apply the derived function of a computer in order to verify its results. 25. f(x) = x2 + 1. (2.5) 26. f(x) = x2 + 2x + 1, (-3,4) 27. f(x) = x3. (2. 8) 28. f(x) = x3 + 1. (1, 2) 29. f(x) = x. (1. 1) 30. f(x) = vx - 1, (5,2) 31. f(x) = x+ (4, 5) 32. f(x) = 1+1( 0,1)
