Question

If f(x) = 4^x - 8 and g(x) = 5x + 6, find (f - g)(x)

Answer 1

Answer:

$4^x-5x-14$

Step-by-step explanation:

$f-g=(4^x-8)-(5x+6)=4^x-8-5x-6=4^x-5x-14$

Answer 2

Answer:

The value of  $(f-g)(x)=4^x-5x-14$

Step-by-step explanation:

Given : If $f(x) = 4^x-8$ and $g(x)=5x+6$

To find : The value of  $(f - g)(x)$?

Solution :

$f(x) = 4^x-8$

$g(x)=5x+6$

We can write, $(f-g)(x)=f(x)-g(x)$

Substitute the value of f(x) and g(x)

$(f-g)(x)=4^x-8-(5x+6)$

$(f-g)(x)=4^x-8-5x-6$

$(f-g)(x)=4^x-5x-14$

Therefore, The value of  $(f-g)(x)=4^x-5x-14$
