Answer 1

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.

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.

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

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.

Answer 2

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.

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.
