How to find vertical asymptotes correct answer: The vertical asymptotes will occur at those values of x for which the denominator is equal to zero How many vertical asymptotes can a graph have? correct answer: infinite When will the graph have at least one horizontal asymptote at y=0 (the x-axis) correct answer: if mn ; the degree of the denominator is larger than the degree of the numerator When will the graph have no horizontal asymptotes correct answer: m n; the degree of the numerator is larger than the degree of the denominator. What is the horizontal asymptote if the degree in the numerator is equal to the degree of the denominator? correct answer: y= a (sub) n / b (sub) n (the coefficients so 4x^2/x^2; the horizontal will be at y=4) If the limits from the left and right are two different values, the limit of f(x) _____ _____ _____ correct answer: does not exist In a box and whiskers plot the vertical line represents the ______ of the data. correct answer: Median In a box and whiskers plot the boxes represent the upper and lower quartile _______ correct answer: medians The relative frequency of an item in a data set is found by ____ the number of times that item appears in the data set by the _____ ____ of items in the data set. correct answer: dividing; total number If the data is symmetrical in a normal distribution and and you are asked the percentage of something being greater than two standard deviations then the percentage will be ____ correct answer: 2.5% In a confidence interval of (x,y) then what can we say at the 95% confidence level. correct answer: There is 95% confidence that between x% and y% of _____ will do/be/vote for _____.
