Question

Select the correct answer.
What is the domain of this function?
f(x) = − 1/4|2x + 1| - 1

Answer 1

A
`(- \infty, \infty)`

Explanation:

Domain is the set of value the independent variable (in our case, x) can take. Absolute value gives no restriction on the set, so the domain is the set of real numbers
`\mathbb{R}`, or
`(- \infty, \infty)`
