Question

Let f(x)=3x-4 and g(x)10-x.what is f+g and what is it’s domain?

Answer 1

2x + 6

Domain: All real numbers

Explanation:

Step 1: Define

f(x) = 3x - 4

g(x) = 10 - x

Step 2: Find f(x) + g(x)

3x - 4 + 10 - x

2x + 6

Step 3: Domain

Since we can plug in any number x, the domain is all real numbers.
