    geometry

    Hey, guys. I need some math assistance. Here is the task I got - find the minima and maxima of the function f(x)=x4−8x2+5 on the interval [−1,3]
    I'm not good at geometry, and I need some help.
    Maybe someone of the users here can give me a few tips on how to solve it

    Yeehaw
    Graph it and look at the x range between those two points to find the approx maxima and minima

    Thanks for the recommendations! The video you sent is indeed informative; however, tbh, it was complicated for me to spend the whole hour watching it. I found the solution to the task I had on this source https://plainmath.net/secondary/geom...chool-geometry, and it's good that it was step by step. I still have some problems with understanding the solution, but at least I have the task done and can now spend more time studying.

    IIRC, and this has been years since i did highschool math, you need to take the derivative and solve for x. its pretty basic and you should be able to do it. Just study.

    ALternatively graph it with Desmos but im sure its not helping you on a test
