Answer:

inverse of [tex]f(x)=x+2[/tex] is [tex]x-2[/tex]

Step-by-step explanation:

To find the inverse of given function, we replace [tex]f(x)[/tex] by y

[tex]y=x+2[/tex]

interchanging x and y we get

[tex]x=y+2[/tex]

then separating the variable y we get

[tex]y=x-2[/tex]

again replace y by [tex]f^{-1}(x)[/tex], we get

[tex]f^{-1} (x)=x-2[/tex]

and we complete the question·
