If f(x) = 4x² - 4x, f'(5) = ?
Use this to find the equation of the tangent line to the curve y = 4x² - 4x + 2 at the point (-5,122). Write your answer in the form: y = mx + b, where m is the slope:
a) f'(5) = 36, y = 36x + 74
b) f'(5) = 36, y = 36x + 122
c) f'(5) = 16, y = 16x + 74
d) f'(5) = 16, y = 16x + 122
