Given f '(x) = (x + 1)(6 + 3x), find the x-coordinate for the relative minimum on the graph of f(x).

x = -1

Step-by-step explanation:

The easiest way is just to find the antiderivative and graph.  The antiderivative is .  Graphing this with any C shows that is the relative minimum.

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3

you,

good luck on your studies! : )
