Question 725287: Sum, difference, and product of two functions:
Suppose that the functions f and g are defined for all real numbers x as follows.
f(x)=2x^(2)
g(x)=3x
Could you please help me write the expressions for (f+g)(x), (f●g)(x), and evaluate (f-g)(2)

is the same thing as and is the same thing as

The second one is ambiguous. Do you mean (composite) or (product)?

is the same thing as whereas is the same thing as .

Evaluating a function at a value is nothing more than substituting that value for the variable and doing the arithmetic.
