Match the correct graph with the number

8. vertex: (1.-2); axis of symmetry: x=1
domain: all real numbers, range: y >_-2

9. The graph is a vertical stretch by a factor of 5 of the graph of f(x)=x^2

11. vertex: (2,-3); axis of symmetry: x=2
domain: all real numbers, range y <_-3

12. The graph is a vertical sturink by a factor of
of the graph of f(x)=x^2 and a reflection in the x axis

step-by-step explanation:

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
