Let f(x) = 3x + 2 and g(x) =x - 3. Find f(x) - g(x). A. 2x - 1 B. 2x + 5 C. 4x - 1 D. 2x - 5

Question

Algebra 2 , functions. Please help

Answer 1

f(x) = 3x +2 and g(x) = x -3

 

f(x) - g(x) will be the difference between those two functions.

 

3x + 2 - (x - 3) = 3x + 2 -x +3 = 2x + 5

 

The answer is B.
