Given no other restrictions what are the domain and range of the following function f (x) = x^2-2x+2

R = y>=1

Step-by-step explanation:

D = all real numbers R = y>=1.

All polynomials have domain of all real numbers.

For the range, the vertex format is useful;

Y = (X-1) ^2 + 1

Since (X-1) is never less than zero, Y>=1.

That is where the vertex is, at Y=1
