how can i find the local extrema of x-coordinates in this equation?
f(x)=x^4-3x^2+2x
f(x)=x^4-3x^2+2x
"If ab= 0 then either a= 0 or b= 0". Not ab equal to anything other than 0!alex123aaa said:here's my solution i really don't know if this is correct but please correct me so
take the derivative = 4x^3-6x+2
Set it equal to zero and begin solving. 4x^3-6x+2 = 0
4x^3-6x = -2
2x(2x^2-3) = -2
2x^2 - 3 = 0 | 2x = 0
Did you notice that [itex]4(1)^3- 6(1)+ 2= 0[/itex]? Once you know that 1 is a root, you know that x- 1 is a factor. Divide [itex]4x^2- 6x+ 2[/itex] by x- 1 to reduce to a quadratic equation for the other roots.2x^2 = 3 | x = 0
x^2 = 3/2
x = plus or minus the square root of 3/2 and x = 0

Local extrema refer to the points on a graph where there is a maximum or minimum value in a specific region or interval. These points can be found by finding the highest or lowest point within a certain range of values.
To find local extrema, you must first find the critical points of the function by taking the derivative and setting it equal to zero. Then, you can plug in these critical points into the original function to determine if they are a maximum or minimum value.
A local extrema is a maximum or minimum value within a specific interval, while a global extrema is the highest or lowest point on the entire graph. Local extrema can exist within a global extrema, but not the other way around.
Yes, a function can have multiple local extrema. This can occur if there are multiple regions of increasing and decreasing intervals within the function.
Local extrema can be used in many fields of science, such as economics, biology, and physics. For example, in economics, local extrema can help determine the optimal price for a product to maximize profit. In biology, local extrema can help determine the ideal conditions for plant growth. In physics, local extrema can help determine the path of a projectile to reach its maximum height or distance.
