#

we were told to give solution using four step rule

#

how would i do that? i missed the class so i really don't know what to do

daring fox
#

you know this?

peak bramble
#

no i do not sorry

#

should i find guides at youtube for now?

daring fox
#

do you know what a derivative is?

peak bramble
#

nope it's the class i missed earlier

#

i'm a bit familiar with it though i hear it a lot

daring fox
#

do you remember y = mx + b?

peak bramble
#

yess

daring fox
#

great do you remember the two point fourmla?

peak bramble
#

yes

#

i doo

daring fox
#

okay imagine you fix one point

#

and you get the other closer and closer to it and you see how the ratio changes

#

this is what a dervtive is

peak bramble
#

ohhh so it's like the rate of change

daring fox
#

in a single moment

#

yes

peak bramble
#

okayy i see i see

#

how would i start

#

in solving the first question?

#

do i have to follow a certain formula

daring fox
#

you understand that part?

#

anyway if you want to solve this plug your function into the fourmla i gave you and you play a game where you have to avoid dividing by zero if you sub 0 into h if you reach a point you arent sub 0 and you get the answer

#

usually such questions are solved using the chain rule

#

how do i even use the bot here i'm so dumb

drifting bane
#

u can use the quotient rule
