you couldnt sovle the limit?
i can't
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
you know this?
do you know what a derivative is?
nope it's the class i missed earlier
i'm a bit familiar with it though i hear it a lot
do you remember y = mx + b?
yess
great do you remember the two point fourmla?
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
ohhh so it's like the rate of change
okayy i see i see
how would i start
in solving the first question?
do i have to follow a certain formula
look at this f(x+h) - f(x) /h
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
is my answer correct for number 1?
how do i even use the bot here i'm so dumb
u can use the quotient rule
they want you to sovle with the limit
