find the limit if it exists: lim Δx-> (1+Δx)^3-1 / Δx

OpenStudy (anonymous):

what i got so far is 3(Δx)+3(Δx)^2+(Δx)^3 / Δx

OpenStudy (anonymous):

Are you able to expand \[(1 + \Delta x)^{3}\]?

OpenStudy (anonymous):

You're getting there nicely.

OpenStudy (anonymous):

yay

hartnn (hartnn):

now u can take delta x common from numerator.....

OpenStudy (anonymous):

i was about to type that out lol. i got scared i messed up

OpenStudy (anonymous):

(Δx) (3+3(Δx)+(Δx)^2 / Δx

OpenStudy (anonymous):

(3+3(0)+(0)^2

OpenStudy (anonymous):

=3

OpenStudy (anonymous):

Don't get scared, you're doing well. These numbers are not scary. Scary is the numbers for the national debt.

OpenStudy (anonymous):

hahha
