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)

(x))
is the same thing as \ +\ g(x))
and (x))
is the same thing as \ -\ g(x))
The second one is ambiguous. Do you mean (x))
(composite) or (x))
(product)?
is the same thing as \right))
whereas is the same thing as \right)\left(g(x)\right))
.
Evaluating a function at a value is nothing more than substituting that value for the variable and doing the arithmetic.
