How do you find the sum of two functions f(x) and g(x)?

Back

The sum of two functions is found by adding their outputs: (f + g)(x) = f(x) + g(x).

How do you find the difference of two functions f(x) and g(x)?

Back

The difference of two functions is found by subtracting their outputs: (f - g)(x) = f(x) - g(x).

How do you find the product of two functions f(x) and g(x)?

Back

The product of two functions is found by multiplying their outputs: (f ⋅ g)(x) = f(x) * g(x).

How do you find the quotient of two functions f(x) and g(x)?

Back

The quotient of two functions is found by dividing their outputs: (f / g)(x) = f(x) / g(x), provided g(x) ≠ 0.

What is the domain of a function?

Back

The domain of a function is the set of all possible input values (x-values) for which the function is defined.

What is the range of a function?

Back

The range of a function is the set of all possible output values (y-values) that the function can produce.
