Answer:

S-shaped curve is the function .

Explanation:

Given:

Four graphical representation.

The diagrams are :

Parabola (opening on x-axis).

Straight line (parallel to y-axis).

Circle (at the origin).

A S-shaped curve (at the origin).

For a relation to be function we will follow the vertical line test:

Note:

The vertical line test says that a relation is a function if a vertical (up and down) line drawn,passes through the graph or cut across it only at one point.

Parabola (opening on x-axis),Straight line (parallel to y-axis) and the Circle (at the origin) fails this test.

An image is attached with.

So the S-shaped curve is the function.
