for the given function f&g, find the following and state the domain of each result
f(x)=2x+1/9x5; g(x)4x/9x5
a.(f+g)(x)=
what is the domain?
b.(f/g)(x)=
what is the domain?
please show work
answer the following for the given quadratic function

Steve,
1. is answered below on related links
2.
f(x) = x^2+10X+25  11  25
f(X) = (X+5)^2  36
now read off the vertex, which lies on the axis of symmetry.
