Question

If f(x) = 3^x + 10x and g(x) = 2x - 4, find (f + g)(x)

Answer 1

The value of the function (f + g)(x) is
`3^(x)+12x -4`.

Option (D) is correct .

Explanation:

As given the equation in the question be as follow.

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

g(x) = 2x - 4

Thus

(f + g)(x) = f(x) + g(x)

`(f + g)(x)= 3^(x)+10x +2x -4`

Simplify the above

`(f + g)(x)= 3^(x)+12x -4`

Therefore the value of the function (f + g)(x) is
`3^(x)+12x -4`.

Option (D) is correct .

Answer 2

The Answer is D

Explanation:

All you do is add both equations 3^x+10x+2x-4

then you add the like varibles which is 10x+2x=12x

So, the answer is 3^x+12x-4
