What are the excluded values of the function y= -2/5x+40

It is a relation but not a function

Step-by-step explanation:

Given

(3,6) (3,7) (-2,-5) (-9,11)

First of all we have to define both terms: Relation and Function

A relation is a set of ordered pairs containing one element from each set

A relation can be a function only if there is no repetition in domain i.e. no first element in each ordered pair should be repeated.

In the given set of ordered pairs, they are relation as all the ordered pairs have two values.

While the given relation is not a function, as there is repetition in first elements of two ordered pairs i.e. 3 is repeated in (3,6) (3,7)

Hence,

It is a relation but not a function

Answer:

a. x - intercept = (-9, 0)

No, y-intercept

Step-by-step explanation:

Since equation of line is x = - 9,

If we draw a graph of it, we will find that line will go parallel to y-axis intersecting x-axis at (- 9, 0).

Hence,

x - intercept = (-9, 0)

No, y-intercept

is the correct answer.

Answer:

a

Step-by-step explanation:

No y-intercept

X-intercept is (-9,0)
