Question

any help will receive a fanning
Create your own unique quadratic equation in the form y = ax2 + bx + c. Use complete sentences and show all work to determine the following:
•Does the graph open up or down? How do you know? (2 points)
•Explain whether the graph has a maximum or minimum point. (2 points)
•Find the vertex and x-intercepts of the graph. (3 points)
next one is
[9.01], [9.02] Part 1: Solve each of the quadratic equations below. Show your work. (3 points)
x2 − 25 = 0 and x2 = 2x + 15
Part 2: Describe what the solution(s) How are the graphs alike and different.

Answer 1

i get it
then you can be dakohta fanning !

Answer 2

lol be able to helkp?

Answer 3

make up anything
like say \(y=x^2+4x-3\) or anything you like

Answer 4

in my example, since the leading coefficient is positive (it is one) it opens up

Answer 5

since it opens up, it has a MINIMUM but no maximum

Answer 6

first coordinate of the vertex is always \(-\frac{b}{2a}\) which i my example is \(-\frac{4}{2\times 1}=-2\)

Answer 7

second coordinate is what you get if you replace \(x\) by the first coordinate
\[y=(-2)^2+4\times (-2)-3=4-8-3=-7\] so in my example it is \((-2,-7)\)

Answer 8

soo confused

Answer 9

oh and you need the \(x\) intercepts, so i picked a bad example as this one does not factor
you can use the quadratic formula to find them but i find it easier to "complete the square"
\[x^2+4x-3=0\\
x^2+4x=3\\
(x+2)^2=3+4=7\\
x+2=\pm\sqrt7\\x=-2\pm\sqrt7\]

Answer 10

ok lets back up and go slow

Answer 11

Create your own unique quadratic equation in the form y = ax2 + bx + c. Use complete sentences and show all work to determine the following:

Answer 12

pick something
anything that looks like \(y=ax^2+bx+c\) i.e. pick an \(a\) and a \(b\) and \(c\)
make it easy by picking \(a=1\) and a nice even number for \(b\)
let me know what you choose

Answer 13

im so confuzzle

Answer 14

did you pick some numbers? just pick 3
make one of them 1 and one of them even
