Answer 2

k so based off the info we just got, OR what we already know lets solve this!

\[ (f–g)(x) \Rightarrow f(x) - g(x) \]
look at what we're given:
\[ f(x)=2x+4 \]
\[ g(x)=–3x \]
that said, just plug those in the formula above:
\[ 2x+4=–3x \rightarrow 5x=-4 \rightarrow x= \frac{-4}{5} \Rightarrow x= -\frac{4}{5} \]
yes?
