Question 48991: I need help. I need to state the range of the function f(x)= (x-2)^2 + 1
I have solved it this far.....
(x-2) (x-2) + 1
x^2-2x-2x+4 +1
x^2-4x+5 and then I equaled it to zero.
X^2-4x + 5 = 0
Now, I am stuck. Am I doing it right? If I am finding the range I am trying to find Y, right? So I need to solve x so I can find y. But what if I can not go any further?
