Given the function:
f(x) = |x| + 9
g(x) = -6
Determine the value of (f + g)(x)
Solution:
In order to determine the value of (f + g)(x), we simply need to equate the two functions in the one single equation separated by a plus sign which denotes the operation of addition.
(f + g)(x) = ( |x| + 9 ) + ( - 6 )
(f + g)(x) = |x| + 9 - 6
(f + g)(x) = |x| + 3
Final answer:
(f + g)(x) = |x| + 3
