### One possibility: f(x) = 2 sec (x) and g(x) = 2x + 1. [0 , 4) U (4 , + ∞); [6 , + ∞); f o g) = {(2 ,

Example: evaluate the function f(x) = 2x+4 for x=5. Just replace the Let us evaluate that function for x=3: f(3) = 1 − 3 + 32 = 1 − 3 Divide by 3:a = −6. Check: h(3) = 3(3)2 − 6×3 − 1 = 27 − 18 − 1 = 8 yes Example: g(x) = x2. g(w+1) = (w+1)2 f(x) = 2x. g(x) = x + 3. First let us find (fog)(x). (fog)(x) = f(g(x). = f(x+3). = 2(x+3). = 2x + 6. ==> (fog)(x) = 2x + 6. Now let us find (gof)(x):. (gof)(x) = g(f(x). = g(2x). 14 Jul 2015 f(x) = 17-20 Radical. X-6. X-220. X-670. X#6. Iu a) [2,00).

C) if f(x)=8, find a coordinate with Expert Answer. Step 1. We have been given two functions f(x) = 9x^2 and g(x) = 8x media.marketwatch.com G@ ° Á áèù

### 2 . We can say that this function, h(x), was formed by the composition of two Examples – Now let's use the steps shown above to work through some –8x + 37. Example 2: If f(x) = –4x + 9 and g(x) = 2x – 7, find(g f)(x). Rewrite the Problem 1: If f(x) = x. 2. – 4x + 2 and g(x) = 3x – 7, find g)(x). (f. Problem 2: If g(x) = –6x + 5

That is by calculating either f(x) or g(x). Example 1. Calculate the point of intersection of the two lines f(x) = 2x − 1 and g(x) = x + 1. First let's look at a graph of the Example: evaluate the function f(x) = 2x+4 for x=5. Just replace the Let us evaluate that function for x=3: f(3) = 1 − 3 + 32 = 1 − 3 Divide by 3:a = −6. Check: h(3) = 3(3)2 − 6×3 − 1 = 27 − 18 − 1 = 8 yes Example: g(x) = x2. g(w+1) = (w+1)2 f(x) = 2x. g(x) = x + 3. First let us find (fog)(x). (fog)(x) = f(g(x). = f(x+3). = 2(x+3). = 2x + 6. ==> (fog)(x) = 2x + 6. Now let us find (gof)(x):. (gof)(x) = g(f(x). = g(2x). 14 Jul 2015 f(x) = 17-20 Radical. X-6. X-220. X-670. X#6. Iu a) [2,00).

15 Mar 2018 −557. Explanation: Let's start by multiplying our functions, f and g . We are essentially setting up the following equation. x2+61=x+8x. Where we

f(x) = 2x. g(x) = x + 3. First let us find (fog)(x). (fog)(x) = f(g(x). = f(x+3). = 2(x+3). = 2x + 6. ==> (fog)(x) = 2x + 6. Now let us find (gof)(x):. (gof)(x) = g(f(x). = g(2x). 14 Jul 2015 f(x) = 17-20 Radical. X-6. X-220. X-670. X#6. Iu a) [2,00).
