Can someone please help me with problem number 18 in this function inverses assignment? This is algebra 2 by the way. Please show your work.

Answer:
n = 3/g +1 or g (not equal to) -1 and the plotting for the graph is xy = -(y - 3)
Step-by-step explanation: see my attached pics for my work
those small dashes in between the = and 3 is a minus as in -3 (negative 3), sorry for the sloppy hand writing!
and for the plotting with the graph, the point where the two dotted lines intersect is what youre looking for
