If g ( c ) = 19 - c 2 mean
g ( c ) = 19 - c ^ 2 then
g ( c ) = 19 - 4 ^ 2
g ( c ) = 19 - 16
g ( c ) = 3
g(4)= 19 - (4x2)
g(4)= 19 - 8
g(4)= 11
yes good point! does the 2 represent a 2 or C squared (C^2)
It wasn't written correctly, but we understand that usually we write 2C for 2*C, and C2 for C^2 due to typographical difficulties. So she probably meant C².
Thank you for helping out.
