The graph of f', the derivative of the function f, is shown above. which of the following could be the graph of f?

From the zeros of the derivative, it is found that option b could represent the graph of f.

In this problem, the critical points are .

It means that at these points, the behavior of the function changes, either from increasing to decreasing, or from decreasing to increasing. Of the options given, the only function for which this happens is option b, thus it is the correct option.

there has been genes found in the x chromosome of males that have been linked to [homo/hetero]sexuality. in addition to the reign of the x chromosome, a section of chromosome 8 has also been link to, "alot of ppl are so " these facts were proven true after a 2014 study of a gay male and his strait brother. according to newscientist.com,"chromosome 14 and is mainly active in the thyroid, but also the brain. called tshr, it makes a type of receptor protein that recognises and binds to a hormone that stimulates the thyroid. in this way, the gene plays an important role in controlling thyroid function. the fact that tshr seems to be involved in sexual orientation fits with evidence that thyroid function seems to be linked to sexuality."

in conclusion, "ppl are so gay" due to their genetics.
