Take Note: Write the standard form of a quadratic function. Assume a ≠ 0 and use function notation beginning with "f(x)=".
HINT: Your equation should include a, b, and c.

Take Note: Some information about the quadratic function, including the location of the vertex, is "hidden" when the function is written in standard form. That seems like a disadvantage of the form. Identify and describe one advantage of standard form that was named in this lesson?

Take Note: Consider the standard form of a quadratic function.
You can derive a lot of information about the graph of a quadratic function from its coefficients when written in standard form.
Match items on the left with those on the right to complete true statements about the graphs of quadratics that are written in standard form.

Draggable item		Corresponding Item
The line x=-\frac{b}{2a} is		(0, c).
If a > 0,		the axis of symmetry.
If a < 0,		f\left(x\right)=ax^{2}+bx+c,\ \ \ a\ne 0.
f(-\frac{b}{2a}) is		the parabola opens upward.
-\frac{b}{2a} is		the parabola opens downward.
The y-intercept is		the x-coordinate of the vertex.
Parabola is the shape of the graph of		the y-coordinate of the vertex.
