The zeroes of $ f $ are $\underline{-1,1}$.

Work Step by Step

We know that the value of x that makes the output of f zero is known as the zero of a function. Generally, the zero of the function is a coordinate or point of the graph of the function that crosses the $ x-$ axis. Therefore, the graph crosses the $ x-$ axis at the coordinates $ x=-1$ and $ x=1$. Hence, the zeroes of $ f $ are $ x=\underline{-1}$ and $ x=\underline{1}$.
