Step-by-step explanation:
.
Answer:
See below
Step-by-step explanation:


If x=1, then 1-1=0, which implies a vertical asymptote at x=1 since dividing by 0 is undefined.
Start by decomposing the number inside the root into primes
Then group the terms into cubes if possible

rewrite the root
![\sqrt[3]{80}=\sqrt[3]{10\cdot2^3}](https://tex.z-dn.net/?f=%5Csqrt%5B3%5D%7B80%7D%3D%5Csqrt%5B3%5D%7B10%5Ccdot2%5E3%7D)
then cancel the terms that are cubes and bring them out of the root
