Question

Given that f(x) = x + 4 and g(x) = x + 7, find (g - 4(x).

Answer 1

Answer: The value of
`(g - f)(x)=4 .`

Explanation:

Given functions :
`f(x) = x + 4` and
`g(x) = x + 7`

To find :
`(g - f)(x)`

Difference between two functions:
`(u-v)(x)=u(x)-v(x)`

Then,
`(g-f)(x)=g(x)-f(x)`

`=(x+7)-(x+4)=x+7-x-4\\\\=7-4=3`

Hence, the value of
`(g - f)(x)=4 .`
