If f(8) = 7, g(8) = 5, f '(8) = -4, and g '(8) = 6, find the following numbers.(adsbygoogle = window.adsbygoogle || []).push({});

(a) Find (f + g)'(8).

i was tryig to apply the product rule to this by doing (f+g)(8)'+(f+g)'(8).....so 0+(f+g)'(8)...so that would be (-4+6)8...but that is not the right way to do it...

please help me get on the right path...
