Question

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

Answer 1

$f(x) = 13x\\g(x) = 5x - 3\\f(g(x)) = 13(5x-3)\\f(g(x)) = 65x - 39$

Answer 2

Answer:

The value of (f-g)(x) is $3^x+5x+3$.

Step-by-step explanation:

The given functions are

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

$g(x)=5x-3$

We have to find the value of (f-g)(x).

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

$(f-g)(x)=3^x+10x-(5x-3)$

$(f-g)(x)=3^x+10x-5x+3$

$(f-g)(x)=3^x+10x-5x+3$

$(f-g)(x)=3^x+5x+3$

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