By taking the derivative of the function. At the maximum or minimum of a function, the derivative is zero, or doesn't exist. And end-point of the domain where the function is defined may also be a maximum or minimum.

How do you determine the range of a function?

Find the maximum and minimum values that the function can take over all the values in the domain for the input. The range is the maximum minus the minimum.

How can you use the zeros of a function to find the maximum or minimum value of the function?

You cannot. The function f(x) = x2 + 1 has no real zeros. But it does have a minimum.


How do you find minimum and maximum value of calculus?

For the function y = x^(3) + 6x^(2) + 9x Then dy/dx = 3x^(2) + 12x + 9 At max/min dy/dx = 0 Hence 3x^(2) + 12x + 9 = 0 3(x^(2) + 4x + 3) = 0 Factor (x + 1)(x + 3) = 0 Hence x = -1 & x = -3 are the turning point (max/min) To determine if x = 0 at a max/min , the differentiate a second time Hence d2y/dx2 = 6x + 12 = 0 Are the max/min turning points. Substitute , when x = -1 6(-1) + 12 = (+)6 minimum turning point . x = -3 6(-3) + 12 = -6 maximum turning point. When x = positive(+), then the curve is at a minimum. When x = negative (-), then the curve is at a maximum turning point. NB When d2y/dx2 = 0 is the 'point of inflexion' , where the curve goes from becoming steeper/shallower to shallower/steeper. So when d2y/dx2 = 6x + 12 = 0 Then 6x = -12 x = -2 is the point of inflexion. NNB When differentiating the differential answer gives the steeper of the gradient. So if you make the gradient zero ( dy/dx = 0) , there is no steepness, it is a flat horizontal line

How do you get minimum or maximum value of constant in a function?

To find the minimum or maximum value of a constant in a function, you first need to identify if the constant is part of a larger expression or if it stands alone. If it's part of a function, you can analyze the function's critical points by taking its derivative and setting it to zero to find local extrema. Then, evaluate the function at these critical points and the boundaries of the domain to determine the overall minimum or maximum value. If the constant is standalone, it remains unchanged as it does not vary with input.


How do you get a maximum displacement?

To determine the maximum displacement, you need to calculate the peak value of the displacement function. This is done by finding the extreme values (maximum or minimum) of the function, typically by taking the derivative and setting it to zero to find critical points. Once you have these critical points, evaluate the function at those points to find the maximum displacement.


How can you find the extremums in a function?

The general procedure is to find the function's derivative, and then solve for (derivative of the function) = 0. Each of these solutions may be a local maximum or minimum - or none. Further analysis is required. A local maximum or minimum may also occur at points where the derivative is undefined, as well as at the function's endpoints (assuming it is only defined for a certain range, for example, from 0 to 10).


How do you find the range and domain of a graph function?

Assuming the standard x and y axes, the range is the maximum value of y minus minimum value of y; and the domain is the maximum value of x minus minimum value of x.


How do you determine wheather a quadratic function has a maximum or minimum and how do you find it?

In theory you can go down the differentiation route but because it is a quadratic, there is a simpler solution. The general form of a quadratic equation is y = ax2 + bx + c If a > 0 then the quadratic has a minimum If a < 0 then the quadratic has a maximum [and if a = 0 it is not a quadratic!] The maximum or minimum is attained when x = -b/2a and you evaluate y = ax2 + bx + c at this value of x to find the maximum or minimum value of the quadratic.
