Step 1
a) k(x) = -9f(x) - 12g(x) k'(x) = -9f'(x) - 12g'(x) b) k(x) = f(x)g(x) k'(x) = f'(x)g(x) + f(x)g'(x) c) k(x) = f(x)/g(x) k'(x) = (g(x)f'(x) - f(x)g'(x))/(g(x))^2 Show more…

A. (f(x)g(x))' = f'(x)g(x) + f(x)g'(x) B. (f(x)/g(x))' = f'(x)/g'(x) C. (f(x)g(x))' = f'(x)g'(x) D. (f(x)/g(x))' = (f(x)g'(x) - g(x)f'(x))/(g'(x))^2 E. (f(x)/g(x))' = (g(x)f'(x) - f(x)g'(x))/(g(x))^2
Differentiable functions f and g have the values shown in the table below. x | f | f' | g | g' 0 | 2 | 1 | 5 | -4 1 | 3 | 2 | 3 | -3 2 | 5 | 3 | 1 | -2 3 | 10| 4 | 0 | -1 If k(x) = f(x)g(x), then k'(2) = -20 -1 -7 13 -6
