Question 290002: 1 Graph Image Hosted by WoO Pics
2. Identify the vertex.
3. Is the vertex a maximum or a minimum?
4. Compare this graph to the graph of y = –x^2

5. Order the quadratic functions y = -4x^2, y = 1/4 x2, and y = 2x^2 fromwidest to narrowest graph.

+graph%28+300%2C+300%2C+-10%2C+10%2C-90%2C+10%2C+-%281%2F2%29%2Ax%5E2-1%29+
The parabola is in vertex form already (because it has no x term).
y=-%281%2F2%29%2A%28x-0%29%5E2-1

Here's the graph with y=-x%5E2 added.
+graph%28+300%2C+300%2C+-10%2C+10%2C+-90%2C+10%2C+-%281%2F2%29%2Ax%5E2-1%2C+-x%5E2%29+

+graph%28+300%2C+300%2C+-10%2C+10%2C+-10%2C+90%2C4x%5E2%2C+x%5E2%2F4%2C2x%5E2%29+

y=4x%5E2 is in green.
y=%281%2F4%29x%5E2 is in red.
y=2x%5E2 is in blue.
