1. (9m + 6) + (–5m – 6)

a= 4m + 12
b= 14m + 12
c= 14m – 12
d=4m

3. (6h + 1) – (9h + 4)

a= –3h – 3
b= 15h – 5
c= –3h + 3
d= –3h + 5

5. (4x + 4) + (3x + 2 + 1)

a= 7x + 3
b= x + 7
c= 7x + 7
d=8x + 6

Determine the domain and range of the given function. the domain is all real numbers all real numbers greater than or equal to –2{x: x = –2, –1, 0, 1, 2}{y: y = –2, –1, 0, 1, 2}. the range is all real numbers all real numbers greater than or equal to –2{x: x = –2, –1, 0, 1, 2}{y: y = –2, –1, 0, 1, 2}.
