Question

Let the limit as x approaches -9; f(x)=9.

Find limit as x approaches -9; square root of f(x)

Answer 1

yes, thats the problem.

Answer 2

No, I mean, use this to find the answer...\[\huge \lim_{x \rightarrow a} \sqrt {f(x) } = \sqrt {\lim_{x \rightarrow a} f(x) }\]

Answer 3

that's exactly how the problem looks

still confused

Answer 4

so then it should come as 3 ?

Answer 5

thanks

Answer 6

You know what \[\huge \lim_{x \rightarrow -9} f(x) = 9\] and this\[\huge \lim_{x \rightarrow -9} \sqrt {f(x) } = \sqrt {\lim_{x \rightarrow -9} f(x) }\]

Answer 7

Understand?

Answer 8

yes thanks man!
