Question

If f(x)= 5 ^ x + 2x and g(x)= 3x - 6, find (f+g)(x)​

Answer 1

`5^x+5x-6`

Explanation:

`f(x)=5^x + 2x`

`g(x)= 3x - 6`

`(f+g)(x)`

`f(x) + g(x)`

`5^x+2x+3x-6`

`5^x+5x-6`

Answer 2

(f+g)(x)​ is 5^x + 5x - 6

Explanation:

To find (f + g)(x), we are merely adding up all the terms present in both

f(x)= 5^x + 2x and g(x)= 3x - 6. 5^x is unique and cannot be combined with any other term. 2x and 3x can be combined to obtain 5x. -6 is unique.

Thus, the sum (f+g)(x)​ is 5^x + 5x - 6.
