In class we are learning about "Function Notation". Ms. Haskins stated that the most common variables use are f, g, or h am i right? The example she used during class to help us develop what she was teaching was the following:
equation: function notation:
to solve this function notation we substituted in for so it became

You are right f, g, and h are used for function notation (think of "f" for function). So f(x), g(x), and h(x) are functions. So if you have

and they want you to find you simply plug 2c in for x

To figure out which operation you perform, we must remember the order of operations. The common mnemonic is PEMDAS where it stands for:
Parenthesis
Exponents
Multiplication
Division
Addition
Subtraction

According to this order, multiplication has precedence over addition (you would perform multiplication first before addition). So this means we evaluate the exponent first

Square 2c to get note: you are squaring the entire term 2c. So 2 is squared also

Now multiply

Multiply 2 and 2c to get

So g(2c) evaluates to
