Understanding Inverse Functions and Domains

The video tutorial explains how to find the inverse of a given function g(x) = tan(x - 3π/2) + 6 and determine its domain. It involves solving for g inverse by swapping variables and using inverse tangent properties. The tutorial also covers the domain and range of tangent and inverse tangent functions, emphasizing the need to restrict the domain for invertibility. Finally, it concludes with the domain and range of g inverse, highlighting that the domain is all real numbers, while the range is from π to 2π.

What is the initial function given in the problem?

• g(x) = cot(x) - 3π/2 + 6

• g(x) = cos(x) - 3π/2 + 6

• g(x) = tan(x) - 3π/2 + 6

• g(x) = sin(x) - 3π/2 + 6
