Does the relationship {(1,1), (2,1),(3,2), (4,3), (5,5), (6,8), (7,13)} represent a function?

storchak [24]

Answer:

Yes.

Step-by-step explanation:

A function is a set of relations without repetitive domains.

From the given relation, there are no repetitive domains. Thus our relation here is a function.

<u>Example</u><u> </u><u>of</u><u> </u><u>Function</u>

{(1,1), (2,2), (3,3), (4,4), (5,5)}

<u>Example</u><u> </u><u>of</u><u> </u><u>Non-Function</u>

{(1,1), (1,2), (2,3), (3,4), (4,5)}

From this relation, there are two repetitive domains which are 1's. Thus not making the relation a function.

I need help write in line slope-intercept from

prisoha [69]

Answer:

Please check the explanation.

Step-by-step explanation:

The equation for the line in slope-intercept form is

$y=mx+b$

where

m is the slope

b is the y-intercept

For example, a line of the form $y=-3x+2$ can be termed as the line of an equation in slope-intercept form after comparing with it.

$y=-3x+2$

where

$m=-3$

y-intercept = b = 2
