Consider the function
{{MATH_233}}
Does {{MATH_234}} have an inverse? If so, what is it? If not, attempt to
restrict the domain of {{MATH_235}} and find an inverse on the restricted
domain.
{{CMD_236}}
In this case {{MATH_237}} is not one-to-one. However, it is one-to-one on the
interval {{MATH_238}}. Hence we can find an inverse of {{MATH_239}} on
this interval. We plug {{MATH_240}} into {{MATH_241}} and write
{{ENV_242}}
Since the domain of {{MATH_243}} is {{MATH_244}}, we know that {{MATH_245}} is
positive. This means we can take the square-root of each side
of the equation to find that
