If g(x)=f(x)⋅h(x)g(x) = f(x) \cdot h(x)g(x)=f(x)⋅h(x), which expression represents g′(x)g'(x)g′(x) according to the product rule?
f′(x)⋅h′(x)f'(x) \cdot h'(x)f′(x)⋅h′(x)
f′(x)+h′(x)f'(x) + h'(x)f′(x)+h′(x)
f′(x)h(x)+f(x)h′(x)f'(x)h(x) + f(x)h'(x)f′(x)h(x)+f(x)h′(x)
f(x)h′(x)−f′(x)h(x)f(x)h'(x) - f'(x)h(x)f(x)h′(x)−f′(x)h(x)
