Answer:
<h2> <em><u>384</u></em></h2>
Step-by-step explanation:
<em><u>Given</u></em><em><u>, </u></em>
Dimensions of the rectangular prism = 9ft, 12ft and 4ft
<em><u>Therefore</u></em><em><u>, </u></em>
Surface area of the rectangular prism
= 2( lb + bh + lh)
<em><u>Hence</u></em><em><u>,</u></em>
<em><u>Surface</u></em><em><u> </u></em><em><u>area</u></em><em><u> </u></em><em><u>of</u></em><em><u> </u></em><em><u>rectangular</u></em><em><u> </u></em><em><u>prism</u></em><em><u> </u></em><em><u>is</u></em><em><u> </u></em><em><u>384</u></em><em><u> </u></em><em><u>sq</u></em><em><u>.</u></em><em><u> </u></em><em><u>ft</u></em><em><u> </u></em><em><u>(</u></em><em><u>Ans</u></em><em><u>)</u></em>
The coordinates of points in the graph are,
and
Any other point whose first coordinate(the x-co-ordinate) coincides with one of these points will make the relation not a function.
The relation becomes one- to-many relation which is not a function.
It will also fail the vertical line test , if the points are connected with line segments.
One of such point is,
