We conclude that the sum of the functions evaluated in x = 17 is 28.
How to find the sum of the two given functions?
Here we have the functions:
- f(x) = √(x - 1)
- g(x) = 2x - 10
The sum of the two functions is just:
(f + g)(x) = f(x) + g(x)
Replacing the functions there we get:
(f + g)(x) = √(x - 1) + 2x - 10
Now we want to evaluate that in x = 17, that just means that we need to replace the variable "x" by the number 17, so we get:
(f + g)(17) = √(17 - 1) + 2*17 - 10
= √16 + 34 - 10 = 4 + 34 - 10 = 38 - 10 = 28
We conclude that the sum of the functions evaluated in x = 17 is 28.
