(f o g)(-3) = (f(g(-3))
Because g is on the inside, we carry out g first.
g(x) = x^2 - 3
Substitute -3 in for x.
g(-3) = (-3)^2 - 3 = 9 - 3 = 6
g(-3) = 6
Next, carry out f on the result of g(-3)
f(6) = 2(6) - 1
= 12 - 1
= 11
So the answer is 11.
The steps i took into doing these problems did very well for me

Lower price
Computation:
Cost in shop A = £1.60 / 4
Cost in shop A = £0.4
Cost in shop B = £2.70 / 6
