Question

What is the vertex in the quadratic function y = - {x^2} + 4 ? Write your answer as an ordered pair.

Answer 1

do you know what it would look like graphically? :)

Answer 2

not really

Answer 3

hmm okay.
Well :

To find y = -x^2, it will be a REFLECTION of the above graph.. so something like this:

Then our equation is " y = -x^2 + 4" , meaning we have to shift that entire graph UP by 4 units ( from the "+4" part)
so,
