EXPLANATION
Let us make y the subject and call it equation (2)
We put equation (2) in to equation (1)
Simplify to get,
Divide both sides by 31,
We put this value in to equation (2) to get,
We collect LCM to obtain,
The table above gives values of the differentiable functions f and g, and f', the derivative of f, at selected values of x. If g
(x) = f^-1(x), what is the value of g'(4) ?
