Question

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

Answer 1

is just using the equations provided to addbecause if f(x)+(g(x)) them so is the 4x +3x-2 what ever it gives you is the answer

Answer 2

Now, we want to sum two polynomial functions:
\[f:f(x)=4x \]
\[g:g(x)=3x-2\]
So we can say that:
\[(f+g)(x) = (4x)+(3x-2)\]
in order to solve this, we must operate the terms with a similar variable, with that i mean the numbers that have an x on their side:
\[(f+g)(x)= 7x-2\]
and that's the way to do a sum of functions.

Answer 3

I though that you just add them

Answer 4

@KenBenX, do you understand?
