Question

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?
Explain whether the graph has a maximum or minimum point.
Find the vertex and x-intercepts of the graph.

Answer 1

MEDALS FOR ALL pleaseeeeee

Answer 2

are you still there ?

Answer 3

okay, let's make up an easier equation lol to make our lives easier:
Let a = 2, b = 4, c = 4

Answer 4

lol okay... if you can do this problem for me, i promise not to post another... i just really have to bring my grade up.... 58 F right now :(

Answer 5

wait let a = 4

Answer 6

Hey i didn't say u werent allowed to post anymore.

Answer 7

i know :( its just i feel like im annoying yall... i just really need to bring that F up...

Answer 8

so, here's our equation a=b=c=4
y = 4x^2+4x+4, very easy to factor lol

Answer 9

It opens up because a is positive (4>0)

Answer 10

Graph has a minimum point at it's turning point which is when x=-b/(2a) = -4/8 = -1/2

Answer 11

So min:
(-1/2;9/4)

Answer 12

vertex is the same as minimum so (-1/2; 9/4).
x intercept occurs when y=0:
0 = (2x+2)^2, so 2x+2 = 0; 2x=-2; x=-1
(-1;0) is the x intercept.

Answer 13

it has only one x intercept, there done lol

Answer 14

I really appreciate this.. your help probably just boosted my grade. I could've never done all that... I really do appreciate it. you made my day. THANK YOUUU :)))

Answer 15

awwww, np :)

Answer 16

& My grade flew up :))))

Answer 17

awesome!

Answer 18

You're very intelligent!

Answer 19
