Question

If f(x) 3 x-1+ 4 and g(x) 4x-7 what is (f-g)(x)?

Answer 1

Answer:

$(f-g)(x)=3^{x-1}-4x+11$

A is correct

Step-by-step explanation:

Given: $f(x)=3^{x-1}+4$

$g(x)=4x-7$

We are given two function and to find difference of two function

$(f-g)(x)$

$\Rightarrow f(x)-g(x)$

$\Rightarrow (3^{x-1}+4)-(4x-7)$

$\Rightarrow 3^{x-1}+4-4x+7$

$\Rightarrow 3^{x-1}-4x+11$

Hence, $(f-g)(x)=3^{x-1}-4x+11$

Answer 2

Hello : 
If f(x)=  3 ^x-1+ 4 and g(x) = 4x-7
 (f-g)(x) = f(x) - g(x)= 3 ^x-1+ 4  - (4x - 7) 
(f-g)(x) =3 ^x-1-4x +11.....( answer : a)
