Is the relation a function? Why or why not? {(3, –1), (3, 0), (–3, 4), (3, 8)}

Yes; only one range value exists for each domain value.
No; three range values exist for domain value 3.
No; the relation passes the vertical-line test.
Yes; three range values exist for domain value 3.

B

Step-by-step explanation:

An x can't have 2 y values and it still be a function. If it fails the vertical line test, it is not a function.

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 "
