Answer 1

Answer:

Function:

• 1, vertical line
• 2, two lines
• 4, bent line
• 5, line

Not a function:

• 3, circle
• 6, the last bent curve

Step-by-step explanation:

In order to determine whether a graph is a graph of a function or not, you simply look for the ones that do not give two or more y for every x. In other words, imagine a vertical line going from left to right and ask yourself: how many times does the line cross the graph? If you find even a single x which gives two y, the graph is not a function. For examples take a look at the sketches i drew ;)
