What is the first step in sketching the graph of a rational function?
o
a. choosing test numbers to the left and right of each of the
function's zeros and finding the value of the function at each test
number
o
b. using test numbers to find where the function is positive and
where it is negative
o
c. finding the function's zeros and vertical asymptotes and plotting
them on a number line
o
d. sketching the function's graph and plotting additional points as
guides when needed

(co 3) the soup produced by a company has a salt level that is normally distributed with a mean of 5.4 grams and a standard deviation of 0.3 grams. the company takes readings of every 10th bar off the production line. the reading points are 5.8, 5.9, 4.9, 6.5, 5.0, 4.9, 6.2, 5.1, 5.7, 6.1. is the process in control or out of control and why? it is out of control as two of these data points are more than 2 standard deviations from the mean it is in control as the data points more than 2 standard deviations from the mean are far apart it is out of control as one of these data points is more than 3 standard deviations from the mean it is in control as the values jump above and below the mean
