Question

What is the domain of the function f of x equals the square root of 2x minus 4 minus 5

Answer 1

\[\sqrt{2x-4}-5\]?

Answer 2

Yea

Answer 3

then 2x-4 must be greater than equal to 0
\[2x-4\ge0 \rightarrow2x\ge4\rightarrow x\ge2\]

Answer 4

because we cant take the square root of negative numbers, so domain is all x such that that does not happen, domain = \[\{\forall x \in R | x\ge 2 \}\]

Answer 5

So the domain would be all reall numbers?

Answer 6

no, read what I said

Answer 7

x>=2

Answer 8

Never mind I got it thank you
