Find slope functions,
Use the Power Rule. If
, then (Careful!)
Remember that π is just a number, not a variable!
, what is the slope function of ? Use that to find the slope function of .
f(x) = 2(x − 2)4 + 18x
is a horizontal shift of , whose slope function is easy to find with the Power Rule (see hint in part (a)). As for , THINK! Since slopes will shift with the function... will equal a shifted version of '.
