Do the coordinates below represent a
Function or Not a Function?
15 POINTS OR BRAINLIEST???

No

Step-by-step explanation:

First step:Ask yourself what is a function

The answer to this would be: a function is a relation in which each element in the domain is mapped on to one AND ONLY one element in the co-domain.

This definition simply means that if it a function, each x value is mapped on to one and one one y value.

When we look at the coordinates given, all the x values are mapped onto the same y values hence it is not a function

b. an equilateral triangle inscribed in a circle

step-by-step explanation:

we are given the figure of two circles having a triangle inside.

now, we know that,

"when a figure is lying inside an another figure, then the outside figure is known as circumscribed figure and the figure lying inside is referred to as the inscribed figure".

as we see that, the circles are containing the triangle completely.

thus, the circles are the circumscribed figures and the triangle is the inscribed figure.

hence, we get, 'an equilateral triangle is inscribed in a circle'.
