is the function shown in the graph one-to-one?

The correct option is 3.

Step-by-step explanation:

In a one-to-one function every element of the function's codomain is the image of at most one element of its domain.

A function is one-to-one function if it passes vertical line test and horizontal line test. It means each vertical and horizontal line cuts the graph of function at most 1.

The given graph passes the vertical and horizontal line test. It means there exist one output for every input. So the function shown in the graph is one-to-one function.

Therefore, the correct option is 3.

the total estimated nappy use.=10,500,000

step-by-step explanation:

given that on an average the average baby uses 3528 napkins.

in a particular year 2014, the number of births were 299697 in new south wales.

rounding off the number of births to the nearest hundred thousand we have

no of birtsh = 300000

also rounding off the average usage to nearst thousand we get

average use of a baby = 3500

hence total number of nappy estimated to be used = 3500x300000

= 10,500,000

answer is 10,500,000 nappies
