Find the domain of the function f(x) = 1 – 4x/1 + 5x thaaaank you!

OpenStudy (anonymous):

how would I find the domain?

ganeshie8 (ganeshie8):

to find domain, look for where the function is undefined.

ganeshie8 (ganeshie8):

a rational function is not defined when denum=0, so...

OpenStudy (anonymous):

oh okay! it's undefined at.. -1/5? but that's the vertical asymptote??

ganeshie8 (ganeshie8):

thats right !

ganeshie8 (ganeshie8):

so its undefined at x = -1/5, and you will have vertical asymptote at x = -1/5
