Because limF(x) = infinity when x goes to 0 so the y-axis ( x = 0) is the vertical asymptote of this function.
it is simple.
Find the vertical asymptotes (if any) of the graph of the function. (Use n as an arbitrary integer if necessary. If an answer does not exist, enter DNE.)
f(x) = 3/x^2
0 is not the answer? why?
edit: so sorry, the answer is x=0, i don't know i have to type the "x="
