State the implied domain of f(x)=1/v(2x+5)-8 using interval notation

State the implied domain of f(x)=1/√(2x+5)-8 using interval notation

Andrew M.

Please note that the answer given by Michael assumes that the denominator of this equation
is (√(2x+5)-8) and that the equation as given is missing a parenthesis.
 
Otherwise the equation is f(x) = 1/√(2x+5) - 8 which is a different equation.
 
In this case the restrictions are that √(2x+5) > 0 in order to be real and also to not divide by zero.
