Question

F(x) = 12 + 1
(f + g) (x) =
g(x) = 5 - x

Answer 1

Step-by-step explanation: The expression for f(x) is not a valid mathematical equation. It should specify the relationship between x and the output value of f(x). If the correct equation for f(x) is given, we can then find the expression for (f + g)(x) and g(x).

Assuming that the equation for f(x) is as follows:

f(x) = 12 + x

Then, the expression for (f + g)(x) can be found by adding f(x) and g(x):

(f + g)(x) = f(x) + g(x) = 12 + x + (5 - x) = 17

So, (f + g)(x) is a constant function with a value of 17 for all values of x.

And the expression for g(x) was already given:

g(x) = 5 - x
