Question

if f(x)=3^x+10x and g(x)=5x-3, find (f-g)(x)

Answer 1

Answer:

$3^x+5x+3$

Step-by-step explanation:

Given that,

$f(x)=3^x+10x$

and

$g(x)=5x-3$

We need to find (f-g)(x).

We know that,

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

$=3^x+10x-(5x-3)\\\\=3^x+10x-5x+3\\\\=3^x+5x+3$

So, the value of (f-g)(x) is $3^x+5x+3$.
