comment What is $f$? Finding where a function converges pointwise?
@Examin5days, you can ask it as a new question, but, briefly, show that every interval around $0$ contains a tail of the sequence $f_n(x)$ ($\forall x\in[0,1)$) i.e. that no matter how small a positive number $\varepsilon$ you pick, you can find some large $m$ such that $f_n(x)<\varepsilon\quad\forall n>m$.

@Examin5days, $[0,1)$ means the interval $[0,1]$ except for the single point $1$. That's the interval on which $f_n\to0$.

Fair enough. Hopefully they'll both help future readers, as well.

I don't see what this adds to my preexisting answer. (Half-kidding. I know you didn't see mine before posting yours, as mine predated yours by merely eleven seconds; so I'm not suggesting you should not have posted your answer. That said, now that you have seen mine, might I suggest deletion as a duplicate?)
