Example of a function whose domain is [2, infinity]

Step-by-step explanation:

Let us see how.

Our function contains a square root. And we know that we can not find the square root of any negative number as a square always gives you a positive number . Hence reverse can not be possible. Thus

we have (x-2) under square root. thus this number must be greater than or equal to 0

(x-2)≥0

subtracting 2 from both sides we get

x≥2

Hence our function gives result only for values which are greater than or equal to 2. Or the domain of function is [2,∞]

hello, sorry being so rude after all that fighting i found it kind of funny, so as me saying sorry here is an answer!

since the table showed her that   2km = 2000m.

to determine, how many km in 2000m, she would divide by 1000.

= 2000 / 1000 = 2 km.

similarly, for 8000m = 8000 / 1000 = 8 km

cheers to savings
