WebWe may know for what intervals 𝑓 prime is positive, but this does not indicate where the function 𝑓 is positive. We can even sketch a few examples for which 𝑓 is positive on two intervals or maybe one interval, but we really cannot know for sure. To answer this question with any sort of certainty, we need more information about 𝑓 of ... WebQuestion: The following function is positive and negative on the given interval. f(x)=8−2x2 ; [0,4] a.

Web2 de mar. de 2013 · Note that the bottom will always be positive for this function, so you can ignore the bottom for this step. At this point it becomes clear that the function is decreasing on the first interval, increasing on the second, decreasing on the third, and increasing on the fourth. Hope this helps! Edit: Also, you are correct that there are zeros … WebAlso tried to show that f(x) has no turning points over the interval, but I can't seem to get anywhere. The latest idea was to try to find a function such that $ f(x) \geq g(x) \geq 0 $ over (0,1) but this just means I have to deal with 2 functions rather than 1. Has anyone got any ideas how I might proceed? Thanks, John.
