Find the slope of the at the given point [Differential Calculus]

Solution for this exercise. thanks in advance. :D

Diff Calculus. Derivative,slope

1.) y = x(4x-1)^2 , (1/2. 1/2) ans. 5

2.) y = (2x-1)^2(x-2)^3. (1.-1) ans. -1

y' = 1(4x - 1)^2 + 2x(4x - 1)(4) = (4(1/2) - 1)^2 + 2(1/2)(4(1/2) - 1)(4) = 5

2) y' = 2(2x - 1) * 2 * (x - 2)^3 + (2x - 1)^2 * 3(x - 2)^2 * 1
Plug 1 in for x.
