i need to find the vertex and plug in the point but i know how to do that but i jjst dont know how to find the vertex, i put (0.2,2) and got it wrong and idk what to do.

idk im just supposed to find the vertex, there is no relation ig. the instruction are instructed for me to find the vertex

#

at the bottom of the graph

#

and idk how to

flat path
deft trail
#

bro idk what ur sayin

flat path
#

or the x value is

#

oh

#

did you not learn that

deft trail
#

no

flat path
#

what were you taught for vertex

#

we can do it that way

deft trail
#

that at the bottom of the loop, where it ends at the x and y value you put x as x and the y as y amiking (x,y) i tried to do that and got 0.2,2 but it was wrong

#

n im lost abt that bcz ik how to find the vertex but not here idk how im supposed to find it when its between 2 whole numbers

flat yoke
#

I forgot how to do parabola but vertex is fairly simple

deft trail
#

what would you put as the vertex i this situation?

flat path
#

thats strange haha

#

okay so uhhh
try to get the equation of the whole thing

deft trail
#

what would u put as vertex?

#

im js tryna see

flat yoke
#

Are you not allowed to just tell them the answer

deft trail
#

ur allowed but ppl want me to learn rather than giving me the answer

#

cn u tell me the answer

flat path
#

not allowed

#

form hint:
$\a(x-b)(x-c)\$
where b and c are the roots

deft trail
#

ohh this

#

id put 0 for b and 1 for c

#

then its 1-0 1-1?

flat path
#

vertex hint: $\$
the average of the roots $(\frac{b+c}{2})$ is the x-value of the vertex

#

I'm pretty sure you just switched the x and y axis based on what you said

flat path
deft trail
#

bru cn u tell me the vertex so ik where i went wrong

flat path
#

but to find the y value you need to find the equation

#

which is what im trying to do rn

#

i mean you can estimate a random value but its not guaranteed

deft trail
#

ok

flat path
deft trail
#

for x do i put 1 or 0

flat path
#

do you know what roots (or zeros) means

#

for a parabola

flat path
deft trail
#

no

flat path
#

y=9(x+9)(x-4)
like that?

#

oh

#

that is an issue

#

do they want you just to estimate where the vertex is then???

deft trail
#

yes

flat path
#

oh okay then just

flat path
#

remmeber x goes first

flat yoke
flat path
#

and x is the horizontal one

flat path
deft trail
#

to 0,1?

flat path
#

but i wanted to teach a non estimate form

deft trail
#

the*

flat path
deft trail
#

what i put

flat path
deft trail
#

oh nvm

flat path
deft trail
#

yeah i mixxdd up the 2,0.2

#

i js needa find the vertex

flat path
#

yea

flat path
#

but not quite

deft trail
#

can we get into a call

#

i learn better listening

#

or hwo do i fidn thye vertwex without esimating

flat path
#

just do it that

#

way...

#

youll learn exact later for sure

deft trail
#

yeah nvm

#

i did the shut

#

shit

#

n i got

#

1/3(x-2/3)^2 77/27

#

is ts wrong

#

@flat path

flat path
#

uhhh
