Alisiya [41]

Answer:

A) a vertical line does not represent a function.

Step-by-step explanation:

For a relation to be a function for each value of x there must be only one value of y. In other words a function is one in which each value in the domain set corresponds to only one value in the range set.

Let us check for this condition in the give choices:

A) a vertical line

A vertical line is given as x=a which meas it is parallel to y-axis and has infinite number of y values for a single x value.

So, its Not a function

B) y=\frac{5}{9}x-3

For the given equation, on plugging in some x value will give a single y value.

So, its a Function

C) a horizontal line

A horizontal line is given as y=a which meas it is parallel to x-axis and has infinite number of x values giving a single y value.

So, its a Function

D) {(1, 7), (3,7), (5, 7), (7,7)}

For the given set for different x valuesthere is only one y value.

So, its a Function
