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

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).

Answer 2

Answer:

3x + 8

Explanation:

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

and f(x)=5x+3

g(x)= 2x-5

f(x)-g(x)=[5x+3] - [2x-5]

=5x+3-2x+5

(f-g)(x)=3x+8
