Question

What is the domain of the step function f(x) = [2x] – 1?

Answer 1

You have troubles with domains only if you have:

• Denominators
• Roots with an even degree
• Logarithms

In this case, you have neither of these three, so you can compute your function wherever you want. The domain is all real numbers.

Answer 2

d all real numbers......:)
