Question

For questions 1 - 2, use the following functions:
f(x) = 3x - 7
g(x) = 2x - 4
1. Find (f + g)(x)
2. Find (f - g)(x),

Answer 1

Answer:

fx+gx=5x-11

fx-gx=x-3

Step-by-step explanation:

Answer 2

Answer:

1.(f+g)(x)=5x-11

2.(f-g)(x)=x-3

Step-by-step explanation:

1.(f+g)(x)=f(x)+g(x)

=(3x-7)+(2x-4)

=5x-11

2.(f-g)(x)=f(x)-(g)

=(3x-7)-(2x-4)

=3x-7-2x+4

=x-3
