Answer:
Option B is correct
\((f+g)(3)\) = 17
Step-by-step explanation:
Given the functions:
f(x) = 6x+3
g(x) = x-7
Solve: \((f+g)(3)\)
First do:
\((f+g)(x) = f(x)+g(x)\)
Substitute the given values we have;
\((f+g)(x) = 6x+3+x-7 = 7x-4\)
Put x = 3 above we have;
\((f+g)(3) = 7(3)-4 = 21-4=17\)
Therefore, the value of \((f+g)(3)\) is 17
