Answer:
x = -24
Step-by-step explanation:
Answer:
<u>Card:: 17</u>
Step-by-step explanation:
<em>Mean is nothing but all of the numbers added together then multiplied by the amount of numbers that there are. In this case, the mean for all of them are 8.2. When you take away the 17, you would be let with 2+5+8+9/4 this results in 24/4 which equals 6.</em>

Part 1 :

⇾ All the relations are not functions. We can determine ( identify ) whether a relation is function or not by drawing a vertical line intersecting the graph of the relation. This is called the vertical line test.
- If the vertical line intersects the graph of a relation at one point , the relation is a function.
- If it cuts at more than one point , it is not a function. It means that if there are more points of the graph of a relation of a vertical line , same first component ( pre - image ) has more images ( second component ) which is not the function by definition.
( See the attached picture )
- In the picture ' 1 ' , The vertical line ( dotted line ) cuts the graph at one point ( P ). Thus the graph represents a function.
- In the picture ' 2 ' , The vertical line ( dotted line ) cuts the graph at two points P & Q. So, the graph does not represent a function.
Part 2 :
☂ The set of all the images of the elements of domain under the function ' f ' is called the range of a function. In other words , the set of second components of a function is called range. We are given the function :
- {(–2, 0), (–4, –3), (2, –9), (0, 5), (–5, 7)}
The above numbers [ in bold ] are the range of given function. Now, If we arrange these numbers in ascending order, we get ( -9 , -3 , 0 , 5 , 7 ).
Hence , Choice B [ {y | y = –9, –3, 0, 5, 7} ] is correct.
