Answer: That the graphs of the functions never intersect with each other.
Step-by-step explanation:
i guess that this refers for a system of equations.
y = f(x)
y = g(x)
So to solve this, we usually would write:
f(x) = y = g(x)
If that has no solutions, it means that the graphs of f(x) and g(x) never cross eachother.
