System of equations
y=-x-1
y+x=3
solve?

Solve by substitution




Just plug in y=-x-1 into y+x=3

So we get:



Simplify that:



And since that is not true, that means this system of equations has no solutions!

Answers: the graph is translated down 1 unit and the domain and range of g(x) is the same as the domain and range of f(x).
