Answer:

x = - 4

g(x) = 8 {x}^{2}  + 4x

g( - 4) = 8( { - 4)}^{2}  + 4( - 4) \\ g( - 4) = 8 \times 16 - 16 \\ g( - 4) = 128 - 16 \\ g( - 4) = 112

=> g (- 4) = 112.

Hey there! Hello!

I believe what this question (more of a statement) is asking is to identify what a letter that represents an unknown number is called. Most of the time, i refer to it as just a variable, or an unknown variable. It can also be referred to as just an unknown value. 

Feel free to ask me any additional questions if you have any! :-)
