The tangent line to the graph of $\small{y = f(x)}$ at the point $\small{(2,6)}$ has the equation $\small{y = 6x-6}$.

(a) Find $\small{f'(2)}$.

$\small{f'(2)}$ =

(b) Find the instantaneous rate of change of $\small{y}$ with respect to $\small{x}$ at $\small{x = 2}$.

Instantaneous Rate of Change =
