Which represents a function ?

Mathematics

Answer: Second option

Step-by-step explanation: A function is a relation in which each x-coordinate corresponds to exactly one y-coordinate.

For the first table, this would not represent a function.

Notice that the -3 and the -3 correspond to different <em>y</em>-coordinates<em>. </em>In order for a relation to be a function, each x-coordinate must pair with one y-coordinate.

The second relation would be a function because notice that each x-term appears only once with a unique y-term so your answer would be the second one.

For the third table, the 0 gets paired up with two different y-values.

For the last relation, the x-term, -12, gets paired up with 4 and 24 which means that the relation can't be a function.

The diameter of fishing line varies. Fishing lines can have a diameter as small as 2 x 102 inch and as large as 6 x 10-2 inch. H
Reil [10]
Answer:
3 times

Explanation:
We know that:
small diameter = 2 * 10^-2 in
large diameter = 6 * 10^-2 in

We want to know how many times larger is the thin diameter compared to the large one.
We will do this as follows:
large diameter = k * small diameter
where k is the number of times that we want to find
6 * 10^-2 = k * 2 * 10^-2
k = (6 * 10^-2) / (2 * 10^-2)
k = 3

This means that the large diameter is 3 times the small one.

Hope this helps :)

Which table values can be defined by the function y=2x+3
lbvjy [14]

Answer:

beggining poit:3   second point (potentially):  1,5

Step-by-step explanation:

in the y intercept 3 is it so which ever has a 3 as the starting point there could be an option

for the 2x part that is the slope otherwise known as rise over run so what you do is that you turn it to a fraction over or under 1 meaning you rise for 2 and go to the right 1

rise 2

      _

run  1

in order to rise 2 you go up 2 from the y intercept(3) and in order to run you go right since its a positive

once you plot those two dots then you draw a line across
