A function that levels off at a horizontal value has a horizontal asymptote. A function can have more than one vertical asymptote. See

Application problems involving rates and concentrations often involve rational functions. See

The domain of a rational function includes all real numbers except those that cause the denominator to equal zero. See

The vertical asymptotes of a rational function will occur where the denominator of the function is equal to zero and the numerator is not zero. See

A removable discontinuity might occur in the graph of a rational function if an input causes both numerator and denominator to be zero. See
[link] .
A rational function’s end behavior will mirror that of the ratio of the leading terms of the numerator and denominator functions. See

Graph rational functions by finding the intercepts, behavior at the intercepts and asymptotes, and end behavior. See

If a rational function has
x -intercepts at
vertical asymptotes at
and no
then the function can be written in the form
Step 1: Find the mean. To find the mean, add up all the scores, then divide them by the number of scores. ...
Step 2: Find each score's deviation from the mean. ...
Step 3: Square each deviation from the mean. ...
Step 4: Find the sum of squares. ...
Step 5: Divide the sum of squares by n – 1 or N.
The sample of 16 students is taken. The average age in the sample was 22 years with astandard deviation of 6 years. Construct a 95% confidence interval for the age of the population.
Bhartdarshan' is an internet-based travel agency wherein customer can see videos of the cities they plant to visit. The number of hits daily is a normally distributed random variable with a mean of 10,000 and a standard deviation of 2,400
a. what is the probability of getting more than 12,000 hits?
b. what is the probability of getting fewer than 9,000 hits?
