8-68.

Consider the function

*f*(*x*) = 2 +. Homework Help ✎State the domain and range.

Write the equation of the inverse.

State the domain and range of the inverse function.

Sketch a graph. What is the smallest *x*-value you can use before the number under the radical sign becomes negative?

What is the smallest *y*-value that can result from this equation?

Remember that in an inverse, *x* and *y* are interchanged. Reverse the domain and range you found in part (a).
