Question

f(x)=5-2 and g(x)2x+1,find (f-g)(x)

Answer 1

Hi...☺️

Here is your answer...✌️

Given that,
f(x) = 5x-2 ; g(x) = 2x+1

Now,
(f-g)(x) = f(x) - g(x)

= 5x-2-(2x+1)

= 5x-2-2x-1

= 3x-3

= 3(x-1)

Answer 2

The value of (f - g)(x) = 3(x - 1).

Step-by-step explanation:

We have,

f(x) = 5x - 2 and g(x) = 2x + 1

To find, the value of  (f - g)(x) = ?

We know that,

(f - g)(x)  = f(x) - g(x)

∴ f(x) - g(x) = (f - g)(x)

= 5x - 2 - (2x + 1)

= 5x - 2 - 2x - 1

= 3x -3

Taking 3 as common, we get

= 3(x - 1)

Thus, the value of (f - g)(x) = 3(x - 1).
