# Is Infinity an extrema?

## Is Infinity an extrema?

If a limit is infinity or negative infinity, these cannot be considered as the absolute extrema values. 3. The greatest function value is the absolute maximum value and the least is the absolute minimum value.

How do you find the maximum value?

If you have the graph, or can draw the graph, the maximum is just the y value at the vertex of the graph. If you are unable to draw a graph, there are formulas you can use to find the maximum. If you are given the formula y = ax2 + bx + c, then you can find the maximum value using the formula max = c – (b2 / 4a).

Can there be two relative maximums?

Yes, there can exist more than one relative minimums and relative maximums.

### What is the minimum point?

Minimum, in mathematics, point at which the value of a function is less than or equal to the value at any nearby point (local minimum) or at any point (absolute minimum); see extremum. …

How do you write an absolute minimum?

The absolute minimum is the y-coordinate at x = 3 \displaystyle x=3 x=3, which is −10.

Can a local maximum be infinity?

1 Answer. that is a number can approach but not touch infinity, so it could not be that the maximum is infinity.

## How do you know if it’s a relative max or min?

Find the first derivative of a function f(x) and find the critical numbers. Then, find the second derivative of a function f(x) and put the critical numbers. If the value is negative, the function has relative maxima at that point, if the value is positive, the function has relative maxima at that point.

Can a relative minimum be an absolute minimum?

A relative maximum or minimum occurs at turning points on the curve where as the absolute minimum and maximum are the appropriate values over the entire domain of the function. In other words the absolute minimum and maximum are bounded by the domain of the function. So we have: Relative minimum of −9 occuring at x=1,3.

How do you find the minimum?

Looking at this graph, you can see that the minimum point of the graph is at y = -3. The second way to find the minimum value comes when you have the equation y = ax^2 + bx + c. If your equation is in the form y = ax^2 + bx + c, you can find the minimum by using the equation min = c – b^2/4a.

### What is the absolute maximum and minimum of a function?

How do I find absolute minimum & maximum points with differential calculus? An absolute maximum point is a point where the function obtains its greatest possible value. Similarly, an absolute minimum point is a point where the function obtains its least possible value.

How do you know if a graph is minimum or maximum?

If the parabola opens up, the vertex represents the lowest point on the graph, or the minimum value of the quadratic function. If the parabola opens down, the vertex represents the highest point on the graph, or the maximum value.

How do you find maximum and minimum values?

Finding max/min: There are two ways to find the absolute maximum/minimum value for f(x) = ax2 + bx + c: Put the quadratic in standard form f(x) = a(x − h)2 + k, and the absolute maximum/minimum value is k and it occurs at x = h. If a > 0, then the parabola opens up, and it is a minimum functional value of f.
