The function  f(x) = –0.3(x  – 5)2  + 5 is graphed. what are some of its key features? check all that apply. the axis of symmetry is  x  = 5.the domain is {x|  x  is a real number}.the function is increasing over (–∞, 5).the minimum is (5, 5).the range is {y|  y  ≥ 5}.

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
