what is the relationship with the vertex and the roots
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
vertex is the average of the roots
bro idk what ur sayin
no
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
I forgot how to do parabola but vertex is fairly simple
what would you put as the vertex i this situation?
oh
thats strange haha
okay so uhhh
try to get the equation of the whole thing
Are you not allowed to just tell them the answer
ur allowed but ppl want me to learn rather than giving me the answer
cn u tell me the answer
nah
not allowed
form hint:
$\a(x-b)(x-c)\$
where b and c are the roots
doggo with da hat
vertex hint: $\$
the average of the roots $(\frac{b+c}{2})$ is the x-value of the vertex
doggo with da hat
I'm pretty sure you just switched the x and y axis based on what you said
x=0 is not a root (or zero, depending on what you were taught)
bru cn u tell me the vertex so ik where i went wrong
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
ok
so try this
for x do i put 1 or 0
have you ever seen this kind of equation before
no
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???
yes
oh okay then just
you swapped x and y for your coordinate there
remmeber x goes first
That's what I said
and x is the horizontal one
yup ik
to 0,1?
but i wanted to teach a non estimate form
the*
nono like the initial answer you put
what i put
||like i thought you were meant to find the exact but you were randomly guessing which is not good||
oh nvm
like around where is the vertex on the grid, just come up with a point
yea
can we get into a call
i learn better listening
or hwo do i fidn thye vertwex without esimating
okay like if your teacher just wants you to estimate
just do it that
way...
youll learn exact later for sure
yeah nvm
i did the shut
shit
n i got
1/3(x-2/3)^2 77/27
is ts wrong
@flat path
uhhh
