Question

need help with this problem

Answer 1

If you want your questions answered, type the out on here. No one wants to open a suspicious file.

Answer 2

replace u by -2 and see what you get

Answer 3

that is all. the "justification" is because both polynomials (the inside piece) and square root are continuous functions

Answer 4

But what limit laws is this problem following?

Answer 5

\[\sqrt{(-2)^3+3\times (-2)+6}\]

Answer 6

i get
\[2\sqrt{2}\] it is no problems here because square root is continuous. and so is any polynomial. so you can just plug in the number and so long as your answer is not undefined, then you have it

Answer 7

OK I get that its continuous but problem is asking for the appropriate limit laws and there six of them.

Answer 8

name one

Answer 9

like lim f(x) + lim g(x)

Answer 10

does one say that the limit of a square root is the square root of the limit?

Answer 11

oh year its actually 10 rule, its the last one which is number 10

Answer 12

if so use that one. and the limit of the product is the product of the limit and the limit of the power is the power of the limit

Answer 13

you can use them all because you have a square root, a power, and a product

Answer 14

ok, thanks!
