Solution Summary: The author calculates the indicated function and domain in interval notation. The domain is a function for which the function is real and defined.
A student writes the following for the function f(x) = (x-2)/(x^2-8x+8):
"The domain of f(x) is (-infinity,-4) U (-4,+infinity)"
Is this correct? If not, what is the correct domain of f(x)?
What is the output from the function of g(x)=-6-2,with an input of -4
