What is the value of the output for the function, g(c) = 19 - c2, if the input is 4?

Answer 1

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

Answer 2

g(4)= 19 - (4x2)
g(4)= 19 - 8
g(4)= 11

Answer 3

yes good point! does the 2 represent a 2 or C squared (C^2)

Answer 4

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.
