Question
3. Let f(x) = In (5x² + 2x).
Graph both f(x) and f'(x) with your graphing technology.
Find f'(1) , f'(2), ƒ'(3) , ƒ'(-1), f'(-2).
Looking at the graph state an interval where f'(x) < 0.
State an interval where f'(¤) > 0.
Find a value of x where f (x) = 0, if any exist.
Is f(x) defined on the interval - <I<0?
Is f'(x) defined on the interval - SIS0?
Use the Chain Rule to calculate f'(x) by hand. (Write it down here.)
Does your answer match your graph?
