Question

How do I find the equation of a quadratic function with points at (-4,4) & (-2,-4)?  f(x)=?

anonymous · Answer

there are infinitely many that go through those two points...
is this the complete question?  should there be three points given?

anonymous · Answer

(-2,-4) appears to be the Vertex $$f(x)=a(x-h)^2+k$$ http://answers.yahoo.com/question/index?qid=20080117163506AAzqtSs & http://jwilson.coe.uga.edu/emt668/emat6680.f99/jones/instructional%20unit/writingquads.html it appears I will need to grab a tool for scribing.

anonymous · Answer

are you given that (-2, -4) is the vertex?

anonymous · Answer

because you could very well also figure out f(x) if the other point is the vertex.

anonymous · Answer

http://www.radford.edu/~wyang/138/application/node1.html Yes, it is not explicitly stated; however it must be the implication as the point is represented in that location.

anonymous · Answer

in your question, i don't see how it is implied that (-2, -4) is the vertex.
but either way the procedure done with those links should provide you with the solution...

anonymous · Answer

Right, in my question it is not; my apologies, it was implied in the graph I am looking at.
Thank you.
