Let f(x) = 3x + 2 and g(x) = x - 3. Find g(x) - f(x) and state its domain.


4x – 1; all real numbers


–2x – 5; all real numbers


2x + 5; all real numbers


2x – 1; all real numbers

Answer 1

Answer:

see explanation

Step-by-step explanation:

g(x) - f(x)

x - 3 - (3x + 2) ← distribute parenthesis by - 1

= x - 3 - 3x - 2 ← collect like terms

= - 2x - 5

There are no restrictions on the domain of - 2x - 5, thus

domain is all real numbers
