<u>Given:</u>
A composite figure made up of a rectangle and two pentagons.
<u>To find:</u>
The area of the composite shape.
<u>Solution:</u>
If a pentagon has a side length of s and an apothem of a, the area of the pentagon is given by
In the given diagram, the pentagons have side lengths of 8 units and an apothem of 5.5 units.
The area of a pentagon 
sq units.
The area of 2 such pentagons 
square units.
The rectangle has a length of 14 units and a width of 8 units.
The area of a rectangle

Given
--- at-home wins
Required
The proportion of at-home games that were wins
This proportion is represented as:
Substitute values for HW and H
Divide by 20%
Express as fraction
The requirement is that every element in the domain must be connected to one - and one only - element in the codomain.
A classic visualization consists of two sets, filled with dots. Each dot in the domain must be the start of an arrow, pointing to a dot in the codomain.
So, the two things can't can't happen is that you don't have any arrow starting from a point in the domain, i.e. the function is not defined for that element, or that multiple arrows start from the same points.
But as long as an arrow start from each element in the domain, you have a function. It may happen that two different arrow point to the same element in the codomain - that's ok, the relation is still a function, but it's not injective; or it can happen that some points in the codomain aren't pointed by any arrow - you still have a function, except it's not surjective.
