if you like my answer then mark me as branlist

Step-by-step explanation:

Read this as follows: the derivative of y with respect to x is the derivative of the f term multiplied by the g term, plus the derivative of the g term multiplied by the f term. To apply it to the above problem, note that f(x) = (x - 3) and g(x) = (2x2 - 1); f'(x) = 1 and g'(x) = 4x.
