Answer 2

Answer: Domain of f(x) = ⌈2x⌉ – 1 is x.

Explanation:

Given : f(x) = ⌈2x⌉ – 1.

To find : What is the domain of the step function .

Solution : We have given that f(x) = ⌈2x⌉ – 1.

Domain : domain is the set of input values for which function is defined or real.

f(x) = ⌈2x⌉ – 1 is a linear function and it is defined for all real values.

Therefore , Domain of f(x) = ⌈2x⌉ – 1 is x is a real number.
