How to solve functions fog
WebFirst we apply f, then apply f to that result: (f º f) (x) = 2 (2x+3)+3 = 4x + 9 We should be able to do it without the pretty diagram: (f º f) (x) = f (f (x)) = f (2x+3) = 2 (2x+3)+3 = 4x + 9 Domains It has been easy so far, but now we must consider the Domains of the functions. The domain is the set of all the values that go into a function. WebHow to Evaluate Function Composition When a is in the second set of parentheses. Ex. f (g(x)) 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.

WebAssuming that 𝑔 is a linear polynomial function in 𝑥. Then we have: 𝑔 (𝑥 + 6) = 5𝑥 + 8 The variable we use doesn't matter, so to avoid confusion, we will write this functional equation in 𝑘 instead of 𝑥: 𝑔 (𝑘 + 6) = 5𝑘 + 8 Since 𝑘 ∈ ℝ, we let 𝑘 = 𝑥 – 6 where 𝑥 ∈ ℝ. Thus: 𝑔 (𝑥 – 6 + 6) = 5 (𝑥 – 6) + 8 Which we reduce to: 𝑔 (𝑥) = 5𝑥 – 22 WebTo get this answer, you use the blue graph which is representing the values of f (x), You get -5 on the x-axis and trace it down to where the blue curve intersects the line you traced down When you trace the intersection point to the y-axis, you get -2 which is Sal's answer ( 2 votes) Show more...

Step 2: Find the domain of the resultant function f (g (x)) and denote it by B. Step 3: Find their intersection (A ∩ B) which gives the domain of f (g (x)) Example: Find the domain of f (g (x)) when f (x) = 2/ (x - 1) and g (x) = 3/ (x - 2). Solution:
WebNov 22, 2014 · 3. actually you have two equivalent ways to answer this problem , The first one is to find g (1) then substitute the value pf g (1) in any x in the f (x) The other way , as you and @Panphobia said , is to do it like : f (x o g) (1) = 2g (1)+3. . . They are equivalent , you will get the same answer .. (: Nov 22, 2014.
