For this, plug in x for both of the equations(so you don’t do anything because that is how it is written) and then you add them. X-13
Answer:
x - 1
Step-by-step explanation:
(f + g)(x)=f(x) + g(x)
(f + g)(x)=(3x - 7) + (-2x - 6)
(f + g)(x)= 3x - 7 - 2x + 6
(f + g)(x)= 3x - 2x - 7 + 6
(f + g)(x)= x -1
