Question from Angel: the domain of f+g when f(x)=8x+3 and g(x)=1-5x |
Hi Angel,
If $x$ is in the domain of $f + g$ then it is in the domain of $f$ and also in the domain of $g.$ Likewise if $x$ is in the domain of both $f$ and $g$ it is also in the domain of $f + g.$ What is the domain of $f?$ What is the domain of $g?$
