To make it more clear: x is the input of g, and g(x) is the output. However, inputting the output of g into f causes f to output x, which is the input of g. Now, for g(f(x)) = x, it is essentially the same thing. f(x) = output of f and x = input of f. Now, inputting f(x) - the output of f, into g gets you the output x - the input of f. Algebra -> Quadratic-relations-and-conic-sections-> SOLUTION: I need to find the functions (f o g), (g o f),(f o f), and (g o g) and their domains for: 34. f(x) = x^2, g(x) = sqrt(x-3) 38. f(x) = x^2, g(x) = sqrt(x-3) 38.

In mathematics, f o g and g o f are known as composite functions. The function f o g is also represented as f (g (x)) and similarly, function g o f is also represented as g (f (x)).

Suppose that f: A → B and g: B → C are both one-to-one and onto. Prove that gf is one-to-one and onto. Prove further that (gf)−1 =f−1g−1. I have already proven the first part, but the second part has always puzzled me. I have tried assuming x ∈ (gf)−1 but that doesn't lead to nowhere. Nor does x ∈ (gf)−1(t) and showing x = t.To prove that O(max{f(n),g(n)}) = O(f(n)+g(n)), we can use the formal definition of big-O:. f(x) = O(g(x)) if and only if there exists a positive real number M and a real number x 0 such that |f(x)| ≤ M|g(x)| for all x ≥ x 0. The absolute value applied in this definition really is a theoretical issue, as in practice only functions are used in the big-O …Question: 36.

To make it more clear: x is the input of g, and g(x) is the output. However, inputting the output of g into f causes f to output x, which is the input of g. Now, for g(f(x)) = x, it is essentially the same thing. f(x) = output of f and x = input of f. Now, inputting f(x) - the output of f, into g gets you the output x - the input of f. How to Evaluate Function Composition. When a is in the second set of parentheses. Step 1. Plug in the inside function wherever the variable shows up in the outside function. The inside function is the input for the outside function. Step 2. Simplify the expression. (optional) Step 3. Plug in the input.f(input) = 2(input)+3. g(input) = (input) 2. Let's start: (g º f)(x) = g(f(x)) First we apply f, then apply g to that result: (g º f)(x) = (2x+3) 2 .

Generally, f o g ≠ g o f for any two functions f and g. So, composition of functions is not commutative. Using the functions f and g given, find f o g and g o f. Check whether f o g = g o f . From (1) and (2), we see that f o g ...Well, h(x) is f(g(x)), and f(g(x)) is simply the function f, but you replace the x's in the equation with g(x). Let's see what that is: h(x) = f(g(x)) = g(x) + 5/3 = -2x 2 + 5/3. So the question said to find (read: make up) two functions f and g so that f(g(x)) = -x 2 + 5/3 - x 2. Welp, we found those two functions. They are g(x) = -x 2 and f(x ... Two functions f and g are inverse functions if fog(x) = x and gof (x) = x for all values of x in the domain of f and g. For instance, f (x) = 2x and g(x) = x are inverse functions because fog(x) = f (g(x)) = f (x) = 2(x) = x and gof (x) = g(f (x)) = g(2x) = (2x) = x. Similarly, f (x) = x + 1 and g(x) = x - 1 are inverse funcions because fog(x ...
