How do you find all critical point and determine the min, max and inflection given #f(x)=3x^2-4x+1#?
Critical point x=
Minima
No maxima, no inflection point.
Maxima does not exist.

To find all critical points, we first find the derivative of the function, . Then, we set and solve for . The critical points are the values where the derivative is zero or undefined.
Next, to determine whether each critical point corresponds to a minimum, maximum, or inflection point, we examine the sign of the second derivative, , at each critical point. If , the function has a local minimum at that critical point. If , the function has a local maximum at that critical point. If , the test is inconclusive, and we need further investigation.
To find inflection points, we locate the points where the concavity changes, which occurs where or is undefined.
Let's follow these steps:
- Find by differentiating .
- Set and solve for to find critical points.
- Compute by differentiating .
- Evaluate at each critical point to determine the nature of the critical points.
- Identify any inflection points by finding where or is undefined.
Following these steps will help us find the critical points, as well as determine whether they correspond to minima, maxima, or inflection points.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
