The Graph of F(x) = (x^2 -2x -8)/(x+6) has which of the following ?
a) point of discontinuity b) vertical asymptote c) both of the above d) neither of the above
i guess a) not sure, can someone help me
When you see the term (x+6) in the denominator, think of what happens when x=-6... => (x+6)=0, and the function is undefined at the vertical asymptote.
A vertical asymptote is also a point of discontinuity, since the function is not defined at x=-6.
Are you now in a better position to review your answer?
