Let f(x) = 1/(sqrt(x)) and g(x) = 2 - 1/6 x ^ 3 be two functions. For what values of x do the graphs of f and g have tangent lines of the same slope?



Answer :

To determine when two functions have tangent lines of the same slope, you would need to get the derivative of both and set them equal to each other.
