hey need some help with a question im struggeling with:
The equation of a curve is y=f( x ) where f( x )= x2 - 6x +14
a ) complete the square for f, ( x )
b) Hence Sketch the graph of y = f ( x ) and y = f(x+3)
Whats really confusing me is how to complete the square, usually im ok with this as there are two terms for example
Y = ax + bx
y= ax - bx
to that idea, anyway i cant see a way of there being two sets so just need a lil explaining thanks ^^
