if f(x)=3x-2 and g(x)=2x+1, find (f-g)(x)

Answer 1

if f(x)=3x-2 and g(x)=2x+1, find (f-g)(x)

(f-g)(x) means f(x) - g(x)

this means (3x-2) - (2x+1)

subtract like terms 3x-2x = x

-2 - 1 = -3

put it together x-3

(f-g)(x) = x-3

Answer 2

Sierra,

if the function operation is "F minus G of X" then its pretty simple. 3x-2 - (2x+1) = 3x - 2 - 2x + 1 = x-1.

X-1 is your answer.

Hope this helps.
