Equations and Graphs of Exponential Functions Follow directions within each exercise. Remember, the graph of an exponential function
will NOT cross the x-axis (keep this in mind when describing end behaviors)
Complete the table. Then
Describe the end
identify the y-intercept
behaviors of the graph.
and the coordinate
where x = 1.
As x increases (x )
х
у
y
-1
As x decreases (x →-0)
у

Use the frequency distribution, which shows the number of american voters (in millions) according to age, to find the probability that a voter chosen at random is in the 18 to 20 years old age range. ages frequency 18 to 20 5.9 21 to 24 7.7 25 to 34 20.4 35 to 44 25.1 45 to 64 54.4 65 and over 27.7 the probability that a voter chosen at random is in the 18 to 20 years old age range is nothing. (round to three decimal places as needed.)
