They make it all so complicated with all of the complex lines doing their own thing, though this is somewhat straight forward once you see it.
With the Domain, these are the x values that the line covers.
For this, it would be -5 ≤ x ≤ 4, because all of the x values are between these two values.
With the Range, these are the y values that the line covers.
For this, it would be -4 ≤ x ≤ 5, because all of the y values are between these two values.
With the X-Intercepts, these are the x values the line crosses for when the y value is 0.
For this, it would be -3 and -1.
With the max, it is the highest point within a graph, for where the y value is the greatest.
For this, it would be x = 4 at the coordinate (4, 5).
