graph{x^2+1 [-10, 10, -5, 5]}
Explanation:
The last number is the y-intercept- 1, in this case, so (0,1) can be plotted.
The y-values for both x=1 and x=-1 are 1+1, which is 2, so (-1,2) and (1,2) can be plotted.
This is the same for 2 and -2, where (-2,4) and (2,4) can be plotted,
and so on.
(Note that there are no negative y-values.)
