Find inverse for an unrestricted linear function
The function \(f(x)=-3x - 12\) has domain \(\mathbb{R}\). Find \(f^{-1}\), then state its gradient, \(y\)-intercept, and \(f^{-1}(6)\).
Worked practice: inverse linear function
Reverse the linear rule, then check the inverse using the requested value.
