Answer:
The graphs shown is NOT a function.
Step-by-step explanation:
We can use Vertical Line test to determine whether a given relation in the graph is a function or not. A relation is a function if one input results in only one output. If we draw vertical lines on the graph, and any of these vertical line intersect the graph at 2 or more positions, then it means that for one value of x, there are 2 values of y. Hence, for one input, there are more than one outputs. Therefore, the relation will not be a function.
We can see in the attached graph below that any vertical line intersects the graph at 2 positions. Hence, the given relation is graph is not a function.
Apologies for the rough drawing.
You can apply the same technique for the graph of the relation which is not shown, you'll get your answers to fill in the blanks
Answer: 756 students
Step-by-step explanation:
38% of the students participate in sports while 25% of the students participate in hobbies.
The percentage of students in sports of hobbies is:
= 38 + 25
= 63%
There are 1,200 students in the middle school. The students in sports or hobbies is:
= 63% * 1,200
= 756 students
The answer is C. Cause the other ones don’t make sense
