F x x2 1 g x 5 x f g x x2 x 4 x2 x 4 x2 x 6 x2 x 6. Find f g x f g x fg x f 𝑔 x f x x2 g x 2x 1 f. Example 16 let f x x2and g x 2x 1 be two real functions. Solution for x 1 f x x x2 4x 4.
Our math solver supports basic math pre algebra algebra trigonometry calculus and more. Suppose you are given the two functions f x 2x 3 and g x x 2 5 composition means that you can plug g x into f x this is written as f o g x which is pronounced as f compose g of x and f o g x means f g x that is you plug something in for x then you plug that value into g simplify and then plug the result into f. The answer is 4x 2 20x 26 this is a composition of functions f x 2x 5 g x x 2 1 g f x g 2x 5 2x 5 2 1 4x 2 20x 25 1 4x 2 20x 26 f g x f x 2 1 2 x 2 1 5 2x 2 2 5 2x 2 3 g f x f g x.
