b. The highest or lowest point of the graph of a quadratic function is called the _________________.
c. Standard Form of a quadratic equation is: ____________________________.
d. The graph is symmetric about the ___________________ which is x=
e. Vertex form of a quadratic equation is ___________________and the vertex is at the point ( , ).

heres some of my answers =
a/
Parabola
b/
vertex
c/
y = ax2 + bx + c
d/
?
e/
?

Answer 1

Parabola
Vertex
y=ax^2+bx+c
Vertex or A.O.S. (Axis of symmetry) occurs at Max/min of the parabola
The vertex form of a quadratic function is given by
f (x) = a(x - h)2 + k, where (h, k) is the vertex of the parabola

Answer 2

Hope this helps

Answer 3

Yes thanks so much !!

Answer 4

can you help with a few more

Answer 5

The length of a rectangular yard is 5 feet longer than its width, x. The area of the yard is 104
sq ft. Use a quadratic to solve for the width.

Use completing the square to convert from standard form into vertex form: f(x)=x^2=8x=10
