Find and classify all the stationary points of the function f (x) = x^3 - 3x^2 + 8. Stationary points occur when the gradient of the function is zero. They can be visualised on a graph as hills (maximum points), as troughs (minimum points), or as points of inflection. (I would draw all three examples on the screen).
The stationary points are found by differentiating the function to get and then finding the values of 𝑥 for which this derivative is zero. The stationary points are found at 𝑥 = -1 and 𝑥 = -3. To classify the stationary points, we substitute the 𝑥 coordinates of the stationary points into the second derivative.

09.12.2021 · Find and classify the stationary points of the function f (x, y) = x2 + 6y − 3y2 + 10 A firm is a perfectly competitive producer and sells two goods G1 and G2 at $1000 and $800, respectively. The total cost of producing these goods is given by TC = 2Q2 1 + 2Q1Q2 + Q2 2 where Q1 and Q2 denote the output levels of G1 and G2, respectively.
Therefore the stationary points are at x = 0 and x = 2. To classify the points, we must find the second derivative of the function and sub in the x values of the stationary points. If the value of the second derivative is greater than 0 it is a minimum point, if it is less than 0, then it is a maximum point. For this function, the second ...
(+ suggests a minimum, – a maximum, 0 could be either or a point of inflection). • Use the curve's equation to find the y co-ordinate(s) of the stationary ...
Mar 21, 2018 · This answer is useful. 1. This answer is not useful. Show activity on this post. Total demand is Q = Q 1 + Q 2, so. P = a − b ( Q 1 + Q 2). Hence the profit of firm i is given by. π i ( Q i) = Q i ( a − b ( Q i + Q j) − C i). The first order condition for the problem of maximizing profits by choosing Q i is given by π i ′ ( Q i) = 0 ...
How to find and classify stationary points (maximum point, minimum point or turning points) of curve. To find the stationary points of a function we must first differentiate the function. The derivative tells us what the gradient of the function is at a given point along the curve.
The stationary points of a function of two variables ... locate stationary points and how to determine their nature using partial differentiation of the ...
To find the stationary points of a function we must first differentiate the function. The derivative tells us what the gradient of the function is at a given point along the curve. Therefore, should we find a point along the curve where the derivative (and therefore the gradient) is 0, we have found a "stationary point".. This, however, does not give us much information about the nature of the ...
If we know about the derivative we can deduce a lot about the curve itself. Increasing functions. If dy dx. > 0 for all values of x in an interval I, then we ...
To classify the points, we must find the second derivative of the function and sub in the x values of the stationary points. If the value of the second ...
