Using the following table:

For each of the following functions, if they are defined at the given point, find their value.

Otherwise explain why they are undefined.

1. 2f(x) + g(x) when x=3

if i substitute the x then itll be 2f(3)+g(3)=2f(30)+g(40)..what is the next step?

2. 3f(2)-2g(0)

sub again 3f(10)-2g(-20)

3. (1/2)f(g(5))

=(1/2)f(g(5)) how do i proceed from this step?could this possibly be undefined?

4. g(x-3)/f(x+6) when x=3

=g(3-3)/f(3+6) = if i cancel the 3 then if im corrent it would be -3/6?
