Algebra Expressions, Equations, and Functions Domain and Range of a Function 1 Answer VinÃcius Ferraz Jun 14, 2018 #x in (7, 8]# Explanation: #f(1/(x-7)) = sqrt{1/(x-7) - 1}# #x ne 7 and 1/(x-7) - 1 >= 0# #frac{1 - x + 7}{x - 7} >= 0# #(x - 7)(x - 8) <= 0# #7 <= x <= 8# Answer link Related questions How do you determine if (-1, 4), (2, 8), (-1, 5) is a function?
