If f = (1, 2), (2, 3), (3, 4), (4, 5),
g = (1, -2), (3, -3), (5, -5), and
h = (1, 0), (2, 1), (3, 2),

find the following and state the domain

2a. f + g

2b. f - g

2c. f * g

if f(x)=x^2+3 and g(x)=3x-1
then find the following

1d. (fg)(x)

1e. fg(-1)

1f. (f/g)(x)

if f(x)=x^2+3 and g(x)=3x-1
then find the following

1a. (f+g)(x)

1b. (f+g)(3)

1c. (f-g)(x)
