Question

f(x)= 2/sqrt of 3-x
find the domain

Answer 1

so fx=2/3-x

Answer 2

\[\frac{ 2 }{ \sqrt{3-x} }\]

Answer 3

opposite of division is multiply 2*3=6

Answer 4

right

Answer 5

3-6=-3 so x=-3

Answer 6

got it

Answer 7

if so fan me and medal pls thanks

Answer 8

you are supposed to find the domain

Answer 9

domain of what? fx

Answer 10

yeah

Answer 11

i figured it out though

Answer 12

see this right here is how my teacher showed me and i'm showing u she said to me that's how u find the domain I don't know if u were showed another way

Answer 13

the correct answer is {x|x<3} or (-infinite,3)

Answer 14

i'm sorry I just screen shot this and showing my teacher

Answer 15

You cannot square root a negative number and you cannot divide by zero, therefore x cannot equal 3 and cannot be greater than 3. So, x has to be less than 3. The (-infinity, 3) indicates the domain on a graph if you were to plot it. Notice that it is in round brackets instead of square brackets meaning that those values are not included.
