Question

What is the domain of f in the equation f(x)=2(x-1)^2-4

Answer 1

Answer:

$(-\infty, \infty)$

Step-by-step explanation:

There are no restrictions on the possible values of $x$, because you can square any number.

Because $x$ can be anything, the domain is all reals or $\boxed{(-\infty, \infty)}$ which means $x$ can be any real number.
