Can each pencil have a mass of 10.5 grams in a pack of 5 pencils weighing 60 to 95 grams?
kvasek [131]
I don't know if I'm right, but if each pencil is 10.5 grams then you multiply it by 5 ( number of pencils) and you get 52.5, which would not meet the standards of a pack weighing 60 to 95 grams.

Answer:

Option 2: 27 is the correct answer.

Step-by-step explanation:

Given functions are:

f(x) = x^2-2\\g(x) = 4f(x) - 1

As we can see that the function g(x) in written in terms of f(x), first of all we have to find g(x) by putting the value of f(x) in g(x)

So putting f(x) = x^2-2 in g(x)

g(x) = 4(x^2-2)-1\\= 4x^2-8-1\\=4x^2-9

As g(-3) has to be found, putting x=-3 in g(x)

g(-3) = 4(-3)^2-9\\= 4(9)-9\\=36-9\\=27

Hence

Option 2: 27 is the correct answer.
