Question

find the domain: p(x)=2x-9

Answer 1

Since you can plug in any real number, the domain is the set of all real numbers.


So the domain in interval notation is \[\large (-\infty,\infty)\]

Answer 2

All real numbers.

Answer 3

thanks

Answer 4

That's a Linear Equation (you can tell this because "x" is considered to be in the power of 1), and in any case with a linear equation the Domain (which basically is where X has any value), is always all real numbers.
