Question

What is the equation for the vertical asymptote of f(x)= (x+2)/(4x+4)

Answer 1

Try this option:
if
`f(x)= (x+2)/(4x+4)`
then according to

`\lim_(x \to (-1-0)) ( (x+2)/(4x+4))=+ \infty`
and
`\lim_(x \to (-1+0)) ( (x+2)/(4x+4))=- \infty`
an equation for vertical asymptote is x=-1.
The graph of this function is in the attached picture.
