Find the domain for the function f(x) = the quotient of the square root of the quantity x minus 3 and the quantity x minus 5.

Daniel [21]

f(x) = sqrt [( x - 3) / (x - 5)]

well x cannot be 5 because that would make x - 5 = 0.

Also the fraction x - 3 / x - 5 cannot be negative because theres no real square root of a negative.

So x must be <= 3 or > 5
