Please can someone help with this question, kind of understand it but don't feel confident..
A) x^2 - 7x + 2 in the form (x-p)^2
I did (x - 7/2)^2 - 41/4
B) Hence write down the minimum value of x^2 - 7x + 2
Is this just -41/4? I'm not sure
C) Describe the geometrical transformation which maps the graph of x^2 - 7x + 2 onto y= (x-4)^2
I really don't understand this one, please help! Thank you

For b) the minimum value of any equation (x-a)^2 + b is (a,b), so for your equation it is (7/2, -41/4).
For c) I'd suggest just looking at the minimum points, the minimum for yours is above and the minimum of the one given is (4,0) so what would map the point (7/2, -41/4) onto the point (4,0)?
