Answer 2

Domain is the x-axis, do you think that there are restrictions of the domain in this graph

Answer 3

im not sure, how do i find out

Answer 4

let us take x=0
\[y=(\frac{ 1 }{4 })^0=1\]
let us take x=-2
\[y=(\frac{ 1 }{ 4 })^{-2}=\frac{ 1 }{(\frac{ 1 }{ 4 })^2 }=\frac{ 1 }{ \frac{ 1 }{ 16 } }=16\]
let us take x=2
\[y=(\frac{ 1 }{4 })^2=\frac{ 1 }{ 16 }\]
similarly we can put any real value.
so domain is ?
