y=×^2-4
= (×-2)(×+2)
so intersects X axis at 2 and -2.
as there is a translation of (2,0), curve moves to the right twice hence giving roots of 0 and 4. now equation is y=×(×-4)
if this is gcse the teacher will know you copied from somewhere...but ur welcome
The curve y = (x^2-4) is translated by(2 0). Write down an equation for the translated graph.Explain

to translate right by 2, replace x with x-2.
y = (x-2)^2 = 4
The 0 vertical translation does nothing.
As always, get out some graph paper and DRAW THE GRAPHS!
y = (x-2)^2 = 4

oops (x-2)^2 - 4 = x^2-4x+4 - 4 = x^2-4x
sooo what is the answer
