Question

What is the answer for this problem?

if f(x)=3x-1 and g(x)=x+2, find (f-g)(x)
A. 3-2x
B. 2x-1
C. 4x+1
D. 2x-3

Answer 1

This is a problem involving the subtraction of two functions f(x) and g(x):

if f(x)=3x-1 and g(x)=x+2, find (f-g)(x). In other words, find:

f(x) = 3x-1
-{g(x) -(x+2)
-----------------
f(x) - g(x) = 3x - 1 - x - 2 = 2x - 3 (answer)
