I cannot do turning points.
Also, if this is from a test, it can be removed.

But here is a graph of the function.

Take derivitive and set to 0 to find the mins and maxes

y'=3x^2+6x-1
set to zero

0=3x^2+6x-1
solve and get $x=\frac{-3-2\sqrt{3}}{3}$ and $x=\frac{-3-2\sqrt{3}}{3}$
those are the turning points

if ya meant inflection point take 2nd deriviive and set to 0

y''=6x+6
set to o
0=6x+6
-6=6x
-1=x
if we find f(-1) we get 0

the inflection point is at (-1,0)

Answer:

x= - $\frac{1}{32}$

Step-by-step explanation:

First move the x on the right side the the left side. Now your equation is

2x+ $\frac{1}{2}$ = $\frac{3}{8}$ Next move 1/2 to the right side. Now your equation is 4x= $\frac{-1}{8}$ . Next divide both sides by 4 to isolate "x." Now your equation is x= - $\frac{1}{32}$
