Math Problem Statement
This question is to emphasize how our differentiation rules can be used even when it doesn't look like you know enough about a function. (This is a handy trick to use when your formula is very long to write out.)
Set h(x)=1+f(x)g(x) , where f and g are differentiable functions that satisfy
f(−3)=6 ,
f′(−3)=4 ,
g(−3)=5 , and
g′(−3)=2 .
Write down a formula for h′(x) on paper. Using this and the information above, find the value of h′(−3) . Answer: h′(−3)=
