Can someone help me pleaseeeee !! Let f(x)=4x√−2x for x>0. Find the open intervals on which f is increasing (decreasing). Then determine the x-coordinates of all relative maxima (minima).

Question

Let f(x)=4x√−2x for x>0. Find the open intervals on which f is increasing (decreasing). Then determine the x-coordinates of all relative maxima (minima).

1.	f is increasing on the intervals
2.	f is decreasing on the intervals
3.	The relative maxima of f occur at x =
4.	The relative minima of f occur at x =

Notes: In the first two, your answer should either be a single interval, such as (0,1), a comma separated list of intervals, such as (-inf, 2), (3,4), or the word "none".

In the last two, your answer should be a comma separated list of x values or the word "none".

Hi there, I can definitely help!

I first need to ask: when you say f(x) = 4xsqrt-2x are you saying the equation is 4 times the sqrt of -2(x) or are you saying 4(x) times sqrt of -2(x)? Also does the square root end at -2 or -2(x)?
