solution: the steps to sketch the graph of rational function are (1) find x-intercept, (2) find y-intercepts, (3) find vertical asymptotes, (4) find horizontal asymptotes, (5) find coordinates of extreme points and (6) plot all points on coordinate plane and join them by a free hand curve.

explanation:

let the rational function is defined as $r(x)=\frac{p(x)}{q(x)}$ .

the steps to sketch the graph of rational function are,

(1) find x-intercept: to find x-intercept set numerator equal to zero, $p(x)=0$ and find the real values of x.

(2) find y-intercept: to find y-intercept put x equal to zero, $x=0$ and find the values of y.

(3) find vertical asymptote: to find vertical asymptotes set denominator equal to zero, $q(x)=0$ and find the real values of x.

(4) find horizontal asymptotes: to find horizontal asymptotes notice the degree of numerator and denominator.

(i) if $deg(p(x))< deg(q(x))$ then the horizontal asymptote is $y=0$ .

(ii) if $deg(p(x))=deg(q(x))$ then the horizontal asymptote is a horizontal line $y=\frac{a}{m}$ , where a is the leading coefficient of p(x) and m is the leading coefficient of q(x).

(iii) if $deg(p(x))=deg(q(x))+1$ then the there is not horizontal asymptote exist but there is a slant asymptote with slope line $\frac{a}{m}$ , where a is the leading coefficient of p(x) and m is the leading coefficient of q(x).

(iv) if $deg(p(x))> deg(q(x))+1$ then the there is not horizontal asymptote exist.

(5) find the coordinates of extreme points: to find the coordinates of extreme points find the critical points by $r'(x)=0$ where r'(x) is the first derivative of r(x). then find second derivative if $r'(x)> 0$ then it will give point of minima and if $r'(x)< 0$ then it will give point of maxima. put these values of x in the original function to find the y-coordinate of extreme points.

(6) plot all points on coordinate plane and join them by a free hand curve.

therefore, the steps to sketch the graph of rational function are (1) find x-intercept, (2) find y-intercepts, (3) find vertical asymptotes, (4) find horizontal asymptotes, (5) find coordinates of extreme points and (6) plot all points on coordinate plane and join them by a free hand curve.

You are in a room of 22 people (including yourself). each of you has their own deck of 52 cards — assume each deck is well-shuffled, and can be assumed to be fair and independent of each other.1. each you draws the top card of your deck.what is the probability that at least one other person has drawn the same card as you? 2. let x be the number of people who drew a card that was also drawn by at least one other person. for example, if you all drew the same card, x=22, but if you all drew different cards, x=0. what is the expected value of x? 3. consider the same situation as the last question, but this time with 29 people: all 29 of you are in a room with your own decks of cards, and you draw one of them.what is the probability that at least one person draws the ace of spades? 4. let x be the number of the types of card drawn. for example, if everyone draws the same card, x=1, but if everyone draws a different card, x=29. what is the expected value of x?
