2/x+5 find domain f(x) range, inverse function f^-1 domain f^-1, range f-1?

Question

Thanks for help

isnt the inverse 5x-2/x?

i know u switch x and y but arent u suppose to solve after? i am confused >. o

Answer 1

domain is all real except x = -5
range is all real

x=2/(y+5) = y + 5 = 2/x
inv fn y=2/x + 5
domain all real except x = 0
range is all real
