Question

p(x)=x^2-2x+5
What is the domain of p?

Answer 1

All real numbers

Answer 2

range is {5, infinity}

Answer 3

really that was quick

Answer 4

there are no fractions (can't divide by zero)
there are no even root functions (square root) can't get square roots of negative numbers
so there are no restrictions on the domain. x can be any number

range are your y values - if you enter on your calculator you will see that it points up and the +5 is the minimum value thus the [5, infinity)
