Question

Given: F(x) = 3x^2+1, G(x) = 2x - 3, H(X) = x
Find F(x) + G(x) =

Answer 1

`F(x)+G(x)=3x^2+2x-2.`

Solution:

Given data:
`F(x)=3x^2+1` and
`G(x)=2x-3`

To find F(x) + G(x):

Adding two functions which gives another function.

Substitute F(x) and G(x), we get

`F(x)+G(x)=(3x^2+1)+(2x-3)`

`=3x^2+1+2x-3`

`=3x^2+2x-3+1`

`=3x^2+2x-2`

`F(x)+G(x)=3x^2+2x-2`

Hence,
`F(x)+G(x)=3x^2+2x-2.`
