Question

what is the domain of p?
p(x)2- 2x+3

Answer 1

x is 2 to the square just don't know how to write it

Answer 2

p=x^2-2x+3?

Answer 3

p(x)=x^2-2x+3. is that it??

Answer 4

In that case the domain is the entire real axis. You can plug any value in for x as there are no roots or divisions.

Answer 5

thank u for showing me where that sign was Thomas. u are a life saver

Answer 6

If the above equation is written correctly, then @Thomas9 is right.
You start off with \[(-\infty,\infty)\]and then from there you look for any square roots or division by a variable to start eliminating points from the domain, but in this case you have neither. So we are just left with what we started with, \[(-\infty,\infty)\]

Answer 7
