Step-by-step explanation:
First image with two graphs:
1. This is a function (Yes)
The domain is 
The range is ![y\in (-2,2]](https://tex.z-dn.net/?f=y%5Cin%20%28-2%2C2%5D)
2 (that graph from the third image). This is not a function (No)
The domain of this relation is ![x\in (-3,5]](https://tex.z-dn.net/?f=x%5Cin%20%28-3%2C5%5D)
The range is 
Second image (parabola):
This is a function (Yes)
The domain is 
The range is ![y\in (-\infty,0]](https://tex.z-dn.net/?f=y%5Cin%20%28-%5Cinfty%2C0%5D)
Fourth image (cubic parabola):
This is a function (Yes)
The domain is 
The range is
