Question 893426: For each function, find:
a.f'(x)
b.f"(x)
c.f"'(x)
d.f^(4)(x)
f(x)= x^4-2x^3-3x^2+5x-7
Little confused on second derivatives. Can someone help me understand this. Thanks

a.f'(x)
b.f"(x)
c.f"'(x)
d.f^(4)(x)
f(x)= x^4-2x^3-3x^2+5x-7
----
f' = 4x^3 - 6x^2 - 6x + 5
f'' = 12x^2 - 12x - 6
f''' = 24x - 12
f'''' = 24
--------------
See how that works?
f'(x^n) =
