Question

What is the domain of f(x) = 1/x

Answer 1

Answer:

(-∞,0)∪(0,∞)

Step-by-step explanation:

So we know that the domain is whatever X can be. We can do that by graphing the function. When we graph the function, you see that there is always an X value except at 1 point. That one point happens to be when x=0, and when x=0, the function also happens to be undefined (no number can be divided by 0). That is why the graph looks so weird. So, the answer would be

(-infinty,0) U (0, infinity)
