Answer:
(r o g)(2) = 4
(q o r)(2) = 14
Step-by-step explanation:
Given
![g(x) = x^2 + 5](https://tex.z-dn.net/?f=g%28x%29%20%3D%20x%5E2%20%2B%205)
![r(x) = \sqrt{x + 7}](https://tex.z-dn.net/?f=r%28x%29%20%3D%20%5Csqrt%7Bx%20%2B%207%7D)
Solving (a): (r o q)(2)
In function:
(r o g)(x) = r(g(x))
So, first we calculate g(2)
![g(x) = x^2 + 5](https://tex.z-dn.net/?f=g%28x%29%20%3D%20x%5E2%20%2B%205)
![g(2) = 2^2 + 5](https://tex.z-dn.net/?f=g%282%29%20%3D%202%5E2%20%2B%205)
![g(2) = 4 + 5](https://tex.z-dn.net/?f=g%282%29%20%3D%204%20%2B%205)
![g(2) = 9](https://tex.z-dn.net/?f=g%282%29%20%3D%209)
Next, we calculate r(g(2))
Substitute 9 for g(2)in r(g(2))
r(q(2)) = r(9)
This gives:
![r(x) = \sqrt{x + 7}](https://tex.z-dn.net/?f=r%28x%29%20%3D%20%5Csqrt%7Bx%20%2B%207%7D)
![r(9) = \sqrt{9 +7{](https://tex.z-dn.net/?f=r%289%29%20%3D%20%5Csqrt%7B9%20%2B7%7B)
{
![r(9) = 4](https://tex.z-dn.net/?f=r%289%29%20%3D%204)
Hence:
(r o g)(2) = 4
Solving (b): (q o r)(2)
So, first we calculate r(2)
![r(x) = \sqrt{x + 7}](https://tex.z-dn.net/?f=r%28x%29%20%3D%20%5Csqrt%7Bx%20%2B%207%7D)
![r(2) = \sqrt{2 + 7}](https://tex.z-dn.net/?f=r%282%29%20%3D%20%5Csqrt%7B2%20%2B%207%7D)
![r(2) = \sqrt{9}](https://tex.z-dn.net/?f=r%282%29%20%3D%20%5Csqrt%7B9%7D)
![r(2) = 3](https://tex.z-dn.net/?f=r%282%29%20%3D%203)
Next, we calculate g(r(2))
Substitute 3 for r(2)in g(r(2))
g(r(2)) = g(3)
![g(x) = x^2 + 5](https://tex.z-dn.net/?f=g%28x%29%20%3D%20x%5E2%20%2B%205)
![g(3) = 3^2 + 5](https://tex.z-dn.net/?f=g%283%29%20%3D%203%5E2%20%2B%205)
![g(3) = 9 + 5](https://tex.z-dn.net/?f=g%283%29%20%3D%209%20%2B%205)
![g(3) = 14](https://tex.z-dn.net/?f=g%283%29%20%3D%2014)
Hence:
(q o r)(2) = 14
