take the derivative:
-4πcos(πx)
cosx=0 for (2n+1)π/2 n∈Z
so check if any of those align=
πx=(2n+1)π/2
x=(2n+1)/2

#

all of them do

supple trail
#

yeah so

#

every option is correct right?

#

answer seemed suspect which is why i had to ask

strong bison
#

yeah all of them are

8x³-6x²=2
solve that for roots

#

only 1 real root, and that's at x=1

supple trail
#

yes I did that step

#

but how does that help me?

strong bison
#

uhm

#

you notice that x=1 isn't any of those options

supple trail
#

yes

#

lol

strong bison
#

so it's none of the above

supple trail
#

hmm

strong bison
#

ohhh

#

I misread the question

#

my bad

#

you do 8x³-6x² where x=2
so 64-24
40 is your slope
now you gonna resolve your intercept:
40(2)+c=2(2)⁴-2(2)³-12=4
80+c=4
c=-76

so your function is y=40x-76

#

check if those points are on the line
