F(x)= x −5. Find f–1(x) and its domain. A.{f^{ - 1}}\left( x \right) = {\left( {x + 5} \right)^2}f −1(x)=(x+5) 2 ; x ≥ –5
B.{f^{ - 1}}\left( x \right) = {x^2} + 5f −1 (x)=x 2+5; x ≥ 0
C.{f^{ - 1}}\left( x \right) = {\left( {x + 5} \right)^2}f −1 (x)=(x+5) 2 ; x ≥ 0
D.{f^{ - 1}}\left( x \right) = {x^2} + 5f −1 (x)=x 2 +5; x ≥ –5
it a i need for later
