i don't know sorry im just answering so i could ask question
y = 3x + 1
It's a linear function. The domain of linear function is the set of all real numbers.

Graph is accurate enuf so that you can determine immed that the vertex / minimum is at (3,-4) and that the y-intercept is at (0,5).
If by "solutions" you mean "roots," the roots are {1, 5} (where y=0).
