Answer:
[1,2], [2,1], [3,0]
Step-by-step explanation:
To find F-1(x) if F(x)=x+3 we just need to put -x instead of x.
From our graph(attached) we multiply any three solutions by a -1:
[tex]F-1(x)\\\\#For \ x=1\\F-1(1)=-1+3=2\\\\#For \ x=2\\F-1(2)=-2+3=1\\\\#For \ x=3\\F-1(3)=-3+3=0[/tex]
Hence, the 3 solutions are [1,2],[2,1],[3,0]
