Finding the rate or time in a word problem on continuous exponential growth or
decay
The number of bacteria in a certain population increases according to a continuous
exponential growth model, with a growth rate parameter of 6.7% per hour. How many
hours
This passes the vertical line
test. It is impossible to draw a
vertical line that intersects the
graph more than once. So the
graph does represent a
function, and the answer is Yes.
This passes the vertical line
test. It is impossible to draw a
0 Domain of the functionf:
The numbers that appear as xcoordinates of points on the graph make up the two intervals
[71, l] and (4, 5). This can be seen by projecting the graph onto the x-axis, as shown in red
in Figure 1.
So, the domain of the function i

To rent a certain meeting room, a college charges a reservation fee of $47
and an additional fee of $6.80
per hour. The film club wants to spend less than $94.60
on renting the meeting room.
94.60 - 47 = 47.60
Therefore:
47.60 / 6.80
= t < 7 hours
