Is the relation a function? Why or why not? {(–5, 7), (–2, –1), (0, 3), (4, 7)}

Yes; only one range value exists for each domain value.

No; two domain values exist for range value 7.

Yes; two domain values exist for range value 7.

No; the relation passes the vertical-line test.

Since you can only have 1 output for the inputs, the correct answer would be A- only one range value exists for each domain value.

Step-by-step explanation:

B. Yes; only one range value exists for each domain value.

Step-by-step explanation:

A relation is considered a function only if for each domain value (the values that x-variable takes) only one range value exists (the values that y-variable takes). In this case, the values taken by the x-variable are: -5, -2, 0 and 4; all in different points.

It doesn't matter that two domain values (or more) have the same range value.

step-by-step explanation: a reaction is first order. if the initial reactant concentration is 0.0200 m, and 25.0 days later the concentration is 6.25 x 10-4 m, then its half-life is:

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 "
