Find equation of tangent line, derivatives if $g(x)= xf(x)$, where $f(3)=4$ and $f'(3)=-2$, find an equation of the tangent line to the graph of $g$ at the point where $x=3$
The help would be appreciated
Thanks!

Hint: $g'(x) = f(x)+xf'(x)$ by the product rule. Now you have a slope of $g'(3)$ and you can get the y-intercept from what was given to you.
