Ineed some with quadratic function

Y= (x-2)² + 5. We can write it as :  y-5 = (x-2)². The general equation of a quadratic function is :

(y-k) = a(x-h)², where h and k are the vertex of the parabola and a, the coefficient which determines whether the parabola opens upward or downward.
So, y-5 = (x-2)²
 Having said that we can say that the VERTEX( 2,5) and since a=1 (a>0) the parabola is open upward OR it passes by a MINIMUM (Then the vertex is minimum)
The domain (x- value) is all Real { x|x = -∞ to x=+∞}
The Range (y-value) is all y ≥ 5

31 is prime. and it’s prime factorization is just 31.
