 Not enough information

anonymous · Answer

y=(x-2)^2

debbieg · Answer

Each REAL root corresponds to an x-intercept. 

And, a quadratic can have either two real roots, one (repeated) real root, or two complex roots.

anonymous · Answer

will it be this  Perfect Square Trinomial

debbieg · Answer

Right. Because a perfect square trinomial has a single, repeated root.

anonymous · Answer

such that my equation shows

debbieg · Answer

It is of the form:

$y=(x \pm c)^2$

anonymous · Answer

like the equation i stated above

anonymous · Answer

ok

debbieg · Answer

Yes, per the equation that @hothand621 gave you. But I think it's more important to understand WHY the types of roots relate to the equation the way they do. That's what the problem is trying to teach.

debbieg · Answer

The problem didn't ask for the equation, after all. It asked how the graph relates to the type of quadratic that it is. :)

anonymous · Answer
