Question 1167086: .If 'f' what is the largest possible domain of 'f(x)=(x+2)^(2)-1,' so that its inverse is also a function? Explain each step. Answer by solver91311(24713) (Show Source):
This function is quadratic, so the graph is a parabola. The axis of symmetry divides the -axis into two parts. The half-open interval on either side of that point is a sufficiently restrictive domain for the function such that the inverse function exists.
