Answer 1

Answer:

a) It is a function as for each  $x-$value there is only one $y-$value.

b) It is not a function because at certain points for a single  $x-$value there are more than one $y-$values.

c) It is a function because for each  $x-$value there is only one $y-$value.

d) It is a function because for each  $x-$value there is only one $y-$value.

Step-by-step explanation:

For a relationship between two quantities to be a function, each $x-$value of the function must have only one $y-$value. If for a particular  $x-$value there are more than one $y-$values then that is not a function.

Based on the graphs (a),(b),(c) and (d) we can conclude:

a) It is a function as for each  $x-$value there is only one $y-$value.

b) It is not a function because at certain points for a single  $x-$value there are more than one $y-$values.

c) It is a function because for each  $x-$value there is only one $y-$value.

d) It is a function because for each  $x-$value there is only one $y-$value.

Answer 2

Answer:

Answer:

a) It is a function as for each  value there is only one value.

b) It is not a function because at certain points for a single  value there are more than one values.

c) It is a function because for each  value there is only one value.

d) It is a function because for each  value there is only one value.

Step-by-step explanation:

For a relationship between two quantities to be a fvmmv unction, each value of the function must have only one value. If for a particular  value there are more than one values then that is not a function.
