Question

Which of the following is true for the rational function f(x)=x-4/x^2-16. A)The vertical asymptotes is x=4. B) The zero of the function is a 4. C)=The vertical asymptote is x=-4. D) The zeros of the function are 4 and -4.

Answer 1

`f(x)= (x-4)/(x^2-16)`

some things true about it
there is a vertical assymtote at x=-4
horizontal assymtote is at x=0
no zeroes

answer is C
