Question

can someone make a graph that represents the eqaution y=x^2-4x+4

Answer 1

its a parabola so it has shape U or upsidedown U. Since the coefficient of x^2 is positive then it is U. Now find the x intercepts

Answer 2

ok

Answer 3

x^2-4x+4=(x-2)(x-2)=0 implies the x-intercepts are x=2

Answer 4

also:

\[x^2 -4x +4 = (x-2)^2\]

might help with finding the x intercept ;)
