How do you find the domain and range of #p(x)=x^2-2x+10#?
We know that the polynomial is a "U" shape because the coefficient of the
This is a polynomial hence all real values of
Method 1 (Completing the Square):
Expand the right hand side of the equation and you will get:
Method 2 (Differentiation)
Find the turning point:
From Method 1 and 2, your minimum point is 9. So the range is
