Using the result (8.9) and the rules of Section 8.3.1, find f(x) where f (x) is Data

Question:

Using the result (8.9) and the rules of Section 8.3.1, find f´(x) where f (x) is

(a) 8x4 - 4x (d) (x + 1)x (b) (2x + 5)(x + 3x + 1) (c) 4x(x  3x) - (e) x x + 1 (f) x + 2x + 1 x + 1


Data from Rules

Rule 1 (constant multiplication rule) If y = f(x) and k is a constant then d - (ky) = kdy = kf'(x) d.x dx

Rule 4 (quotient rule) If u = f(x) and v = g(x) then d 40- = dy dx = Rule 5 (composite-function or chain

Rule 7 (parametric differentiation rule) If y = f(x) where x = g(t) and y = h(t) and t is a parameter, then
