True or false: let f(x)=tan^-1x. then the domain of f(x) is all real numbers and the range is [0, pi]

The given answer is FALSE

Step-by-step explanation:

Domain : The domain of a function is the set of values for which the function's value is real and defined.

So, The domain of the given function will be all real numbers

Interval Notation : -∞ < x < +∞

Range : The set of values of the dependent variable for which the function is defined.

The basic arctan function is only defined for :

So, The range of the given function is :

Therefore, The given answer is FALSE

the answer   is 200

step-by-step explanation:

this is a problem about poisson probabilities.   i don't know if you've

already studied poisson distributions, or if you have a place to look

to read more about the subject.  

here's how you can see a poisson distribution coming.   when there are

a lot of events that may happen at any time (or any place), and when

you're counting how many of them happen at a particular time (or a

particular place), and each event is independent of the others, then

the result is a poisson distribution.   this is roughly true for the

chocolate chips; one chip being in a cookie has only a small effect on

the probability that another chip will be in the cookie.

once you know you have a poisson distribution, you know a lot.   there

is only one parameter to a poisson distribution, so if you know the

mean, you know everything.   the form of the distribution is

  probability of n chips = {[e^(-x)]*(x^n)} / (n! )
