Given f(x) = 3x − 10 and g(x) = 12x + 8, solve for (f + g)(x) and select the correct answer below. (f + g)(x) = 15x − 2 (f + g)(
x) = 9x − 2 (f + g)(x) = 15x + 2 (f + g)(x) = 36x2 − 120x
2 answers:
(f+g)(x) simple means adding both f(x) and g(x). This means that
(f+g)(x) = 3x-10 + (12x + 8)
= 15x-2
Answer: First option is correct.
Step-by-step explanation:
Since we have given that
We need to find the addition of two functions i.e. f and g.
So, it becomes,
Hence, the addition of two functions is (f+g)(x)=15x-2.
Therefore, first option is correct.
