Question

Given f(x) = - 3x - 2 and g(x) = - 2x - 4 , find h(x) = g(x) - f(x) .

Answer 1

Therefore,

`h(x)=x-2`

Explanation:

Given:

f(x) = - 3x - 2 and

g(x) = - 2x - 4 ,

To Find:

h(x) = g(x) - f(x)= ?

Solution:

We require,

`h(x) = g(x) - f(x)`

Substituting f(x) and g(x) we get

`h(x) = (-2x-4)-(-3x-2)\\\\h(x) =(-2x-4) +3x+2......Minus\ sign\ will\ go\ into\ bracket\\\\\therefore h(x)=x-2`

Therefore,

`h(x)=x-2`
