Answer:
no se no hagas nada de eso
Lna^b = blna
let y = lne^e
so y = lne^e = e lne
lne = 1
y = e which is a constant (Euler's number) ~= 2.718
For Euler's number estimating methods request in a comment.
The answer is g (x) = (1/2) ^x-9 + 5
Just took the test and got an 80% :)
The variable expression is x(shirt cost) + 8. The answer is x+8.
