The point of the form $(a,a)$ always lies on:

1. $x-axis$

2. $y-axis$

3. On the line$y=x$

1. Relation but not a function
2. Function but not a relation
3. Both Relation and a function
4. Neither relation nor function

Q. In the graph given below,
How many maximum values does $y$ can have for one value of $x$?

Q.

Your friend graphs the function represented by the input-output table. Is your friend correct? Explain your reasoning.

Q. If a relation is given in form of equation, then the relation is , if there is no vertical line exists, which intersects the graph of equation at more than one point.

Q. A relation is a function only if it passes the vertical line test.

1. True
2. False

Q.

1. Relation not a Function
2. Function not a Relation
3. Both Relation and a Function
4. Neither Function nor Relation

Q.
The above graph is

1. Not a relation
2. Not a function
3. a function
