Is this a function?

It is not a Function!

Step-by-step explanation:

The easiest way to tell if a graphed line is a function is the Vertical Line Test. If you draw a vertical line across the original line given and it only crosses through a curve once, then it is a function. If it crosses it more than once, it is not a function.

If you drew a line through this graph, it would touch more than one curve at a time, confirming it as a non- function.

Regards!

a net is a diagram that shows a “flattened” view of a solid. in a net, each face and base is shown with all of its dimensions. a net can also serve as a pattern to build a three-dimensional solid.

a pyramid is a three-dimensional object with a base that is a polygon and triangular faces that meet at one vertex.

" the net of a triangular pyramid consists of four triangles. the base here we are given of the pyramid is a equilateral   triangle, and the lateral faces are also triangles "
