The Horizontal Line Test states that; if when drawing a horizontal line to the graph of a function, this line cuts the function at more than one point, the inverse of that function is not a function.

Applying the test for graphs attached:

We can conclude the inverse of graphs number 1, number 2 and number 4, are not functions because the lines cut in mere than one point.
