how do I find the derivative test to determine the location of each extremum and the value of the function at this

extremum

f(x)=5x In |x|

f ( xc ) = Sockn/acl

As we know.
the first derivative determine the slope of
the given function f(31) . when we but of.,
die = 0 le
slope is zero , then at this point the slope line will
be…
