If we take the square root of both sides of this, you get x squared is equal to 9, or so you get x is plus or minus 3. x is equal to plus or minus 3. These are our candidate inflection points. x is equal to 0, x is equal to plus 3, or x is equal to minus 3. What we have to do now is to see whether the second derivative changes signs around these points in order to be able to label them inflection points. What happens when x is slightly below 0? Let's take the situation, let's do all the scenarios. What happens when x is slightly below 0?
