Step-by-step explanation:
For a relation to be a function each value of x on the domain can only map to one unique value of y in the range.
For the given point, we can see that
x = 1 → y = 4 and x = 1 → y = 1
This breaks the function rule, thus the set is not a function

Explanation:
The list of first numbers of the ordered pairs is ...
1, 3, 1, 9, 0.
There is a repeated value, 1, so the relation cannot be a function. Each domain value can only appear once in a relation that is a function.

Step-by-step explanation:
A) Calculate the exact areas of circle P and regular hexagon ABCDEF.
Solution:
Area of circle = πr²
where r= 12 cm
Area of circle = (3.14)(12)²
Area of circle =(3.14)(144)
Area of circle = 452.16 sq cm
Area of hexagon = 3√3 *(side)²/2
Since hexagon is consist of six identical equilateral triangles the side is same as the vertex to center. In this case it is same as the radius
Area of hexagon = 3√3 *(12)²/2
Area of hexagon = 3√3*(144)/2
Area of hexagon = 374.12 sq cm
B) Find the exact area of the shaded region:
Area of shaded region = Area of circle - Area of hexagon
Area of shaded region = 452.16 - 374.12
Area of shaded region = 78.27 sq cm
C) Imagine circle P with regular inscribed octagon ABCDEFGH, rather than regular hexagon ABCDEF. In two or more complete sentences, describe the effect the number of sides of the polygon would have on the area of the shaded region.
Since octagon has 8 sides so it will occupy more area than hexagon. The shaded area will then reduce. The polygon area increases, the shaded area decreases
