What are composite functions and how do you compute values for composite functions?
If f(x) = x^2 - 9 and g(x) = x + 3, what is (f + g)(x)?
If f(x) = x^2 - 9 and g(x) = x + 3, what is (f - g)(x)?
If f(x) = x^2 - 9 and g(x) = x + 3, what is (f * g)(x)?
If f(x) = x^2 - 9 and g(x) = x + 3, what is (f / g)(x)?
If f(x) = x^2 - 9 and g(x) = x + 3, what is (g - f)(x)?
If f(x) = x^2 - 9 and g(x) = x + 3, what is (g / f)(x)?
If f(x) = x^2 - 9 and g(x) = x + 3, what is (f o g)(x)?
If f(x) = x^2 - 9 and g(x) = x + 3, what is (g o f)(x)?
