Which graph shows a set of ordered pairs that represnt a function

The correct option is 2.

Explanation:

If the graph satisfies the vertical line test then it a graph of a function.

According to the vertical line test the graph of the function intersects all vertical line at most once. If a graph intersects any vertical line more that one time then it is nt the graph of a function.

Reason correct option:

Only the graph 2 passes the vertical line test therefore the correct option is 2.

Reason for incorrect option:

In figure 1 the graph intersects the vertical lines x=-2 and x=0 two times, therefore the graph does not pass the vertical line test.

In figure 3 the graph intersects the vertical line x=4 two times, therefore the graph does not pass the vertical line test.

In figure 4 the graph intersects the vertical line x=2 two times, therefore the graph does not pass the vertical line test.

Therefore the option 1,3 and 4 are incorrect.

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.

there are 70 more legs than eyes at the dog show (196 – 126 = 70). dogs have two more legs than eyes, and humans have the same number of legs as eyes. thus 70 is twice the number of dogs at the show, so the number of dogs is half of 70, which is 35. to get the number of humans, subtract 35 from 63: 63 – 35 = 28.
