Consider the function g(x) = 2x/(4x^2 + 7x 2). Which statement is false below? (a) g(x) has two vertical asymptotes. (b) g(x) has the domain in which "x is not equal to 1/4 and 2". (c) g(x) has a horizontal asymptote along y = 0. (d) g(x) has the range in which y is all real numbers. My answer is (b) is false because x = 1/4 and x = 2. The answer key says (b). So, my answer is correct, but shouldn't (d) is false as well? The reason is that g(x) has a horizontal asymptote along y = 0. Did the answer key overlook (d)? Thanks for your help.

No. As y = 0 for x = 0, 0 is in the range.
