**Reiny**, Wednesday, March 23, 2011 at 9:49pmf(x) = x^3 - x^2 + x - 1

f'(x) = 3x^2 - 2x + 1

when x=2 , f'(1) = 12 - 4 + 1 = 9

also when x=2, f(2) = 8 - 4 + 2 -1 = 5

so the tangent has a slope of 9 and passes through (2,5)

equation of tangent is y = 9x + b

at (2.5)

5 = 9(2) + b

b = -13

equation of tangent: y = 9x - 13
