What is the answer? I came up with C. is this correct? Thanks for the help in advance!

f(x)=root sign, and inside that x-2 and g(x)x-7. Which of the following is the domain of the quotient function f/g?

A. (-infinity,2]

B. (-infinity,7) U (7,infinity)

C. [2,7) U (7,infinity)

D. (2, infinity)

sqrt(x-2) /( x-7) ???

x must be 2 or greater or we have the square root of a negative number, which is not real.

x may not be 7 or we have a zero in the denominator

therefore

2 to 7 and 7 to + infinity

Is C the answer?

Is C the quotient function of f/g?
