explanation needed

[hollow matrix]

just don't understand really

[jade turret]

which

or what

[hollow matrix]

5b-e

Im pretty lost all together

as to what it's asking

[hollow matrix]

mainly the linear equations bit

[jade turret]

local max at 1,4

f(1) = 4

also

f'(1) = 0

[hollow matrix]

hmm

the third?

[jade turret]

point of inflection is when the graph switches its sign

[hollow matrix]

OH I read it as

nvm lmao

sorry

[jade turret]

like concave up and down

so

[hollow matrix]

I was reading the question wrong

[jade turret]

f''(x) = 0

[hollow matrix]

I thought it wanted me to represent something else

[jade turret]

its basically just a system of equations

[hollow matrix]

yeah nw thank you

@jade turret ok but then how does that help me solve for a b and c

sorry for ping

or rather like 5 pings alltogether

[jade turret]

f(1) = 4

4 = a + b + c

f'(1) = 0

[hollow matrix]

oh.

[jade turret]

0 = 3a + 2b + c

[hollow matrix]

yeah

[jade turret]

wait

[hollow matrix]

thank you lots akaza

[jade turret]

yes

[hollow matrix]

yes

[jade turret]

f''(2) = 0

0 = 6a*2 + 2b

i think i did correctly but idk, you get the idea

[hollow matrix]

yeah I'm like 30% you did it right

👍

[hollow matrix]

I'm confused again, what exactly do I do with this?

[jade turret]

solve for something

0 = 12a + 2b

b= -6a

c = 4 - a - b

c = 4 - a -(-6a)

[hollow matrix]

my poor head 🤕

I think I get it

[jade turret]

then set it in this

[hollow matrix]

4a = 4?

[jade turret]

idk i didnt calculate it

i gave you idea how to solve

[hollow matrix]

fair enough

[jade turret]

dont you have answers to it or sometgn
