determine when the function is decreasing,increasing and find the relative extrema points.
a. f(x)= (x^2 - 9)^2
b. f(x)= (2x^2)/(x-2)
NB ' / ' MEANS DIVIDES AND '^' MEANS TO THE POWER

2.indicate all key features ie intercept,interval of increasing and decreasing,and relative extrema by sketching the graph of the function f(x)= x^4+6x^3+9x^2.
NB ' ^' MEANS TO THE POWER
I only want the working of the problem and not the sketches please.

A question was asked
"Briefly describe how genetic and physical maps of a genome are constructed,
indicating techniques that are used, and how they have been used in genome sequencing projects"


My answer would be genetic maps are made by cloning cut fragments of DNA into vectors and sequecing. The locations of these fragments on each chromosome would be know because they would be linked to genetic markers such as microsatelites. They have been used in genome sequencing projects because the allow a refrence to which further genomic sequencing can by done by overlaping clones of the marker DNA.
Is there anything I could add missing?

as per eienstine's relativity moving body increses it's mass when it travel with high speed,at speed of light mass is infinite.photon has mass it is very less,but it has little mass which should be increse when it gets the speed of light.

at the start of her trip on a pleasant afternoon at 22C, a driver's car tires have a pressure of 2.9x10^5 Pa. The pressure rises by 33% during her trip. Ignoring the expansion of the tires, find the temperature of the tires at the end of her trip

** can you please show it step by step?

I had my appendix taken out late Tues. night and came home late Wed. afternoon. I was prescribed 5mg percocet for pain and I have had it MANY times in the past for my back, but now when I take it I start to vomit and get ill. Could this be because of the surgery? This also happened when I stopped taking it and tried a tylenol (7 hours after my last percocet). I wasn't anywhere near my tylenol (acetemetaphine) level, but yet it now makes me sick. Do you think a doc would switch meds for me or is this bad to ask being I was able to take percocet before my surgery?

The metre is defined as the distance travelled by light in 1/299792458 second. Why did'nt people choose some easier number such as 1/300000000 second? Why not 1 second?
