Question
Give a rule for each piecewise-defined function. Also give the domain and range.(GRAPHS CANNOT COPY)
Step 1
We know that the function is equal to 1 when $x \neq 0$ and the function is equal to 0 when $x=0$. So, we can write this as a piecewise function: \[f(x) = \begin{cases} 1 & \text{if } x \neq 0 \\ 0 & \text{if } x = 0 \end{cases} \] Show more…
