Question

Could someone please help me?

Answer 1

@Atrineas

Answer 2

Uhh well the vertex has a fraction so I don't know how to do that but I have the Y inter answer and X inter Answer

Answer 3

@TheSmartOne can you help get the vertex please

Answer 4

mm I don't know either but I'll brb I've got some things to do it may to a long time or not but I'll be back as soon as I can

Answer 5

ok

Answer 6

@rebeccaxhawaii can you help her get the vertex plz for the equation
-5x^2-2x-4

Answer 7

sure

Answer 8

K thanks

Answer 9

http://prntscr.com/b1k8h5 that would be your vertex

Answer 10

@rebeccaxhawaii it has to be entered in as a fraction which is why I'm having trouble

Answer 11

That what @Atrineas said and I can't see them website @rebeccaxhawaii my laptop doesn't allowed me too

Answer 12

It's basically takes you to desmos

Answer 13

Oh

Answer 14

A quadratic function is a function of the form f(x)=ax^2+bx+c, where a, b, and c are real numbers and a = 0
for the given function a=-5, b=-2 and c=-4

Answer 15

Okay so it looks like we're trying to get factions for this one

Answer 16

The vertex occurs at x= \[-\frac{ b }{ 2a }\] To find the x-coordinate of the vertex of the given function, substitube the values of a and b into the expression and simplify.
Let a=-5 and b= -2
\[\frac{ -2 }{ 2(-5) }=-\frac{ 2 }{ 10 }\]

Answer 17

Idk maybe. . .

Answer 18

Okay say that \[-\frac{ 2 }{ 10}\] is the x-coordinate, we would evaluate to find the y-coordinate r
\[r(-\frac{ 2 }{ 10 })=-5(-\frac{ 2 }{ 10 })^2-2(-\frac{ 2 }{ 10 })-4=?\]

Answer 19

yes

Answer 20

okay but what would the second part be?

Answer 21

This is for vertex right?

Answer 22

yea

Answer 23

ok so x=-2/10 and y=?
The answer to the last problem you just wrote with all the fractions which Equals
Whatever it equals

Answer 24

The one I got wrong?

Answer 25

so um\[(-\frac{ 2 }{ 10 }, 3)?\]

Answer 26

Or would it be \[(-\frac{ 2 }{ 10 }, -2)\]

Answer 27

Ehto I think y=-4

Answer 28

It says its wrong

Answer 29

I think I figured it out not 100% sure tho

Answer 30

sorry if you can't read it. It was just something I was thinking still don't know if it 100% right
