Answer:
<h2>The value of
is 31 years.</h2>
Step-by-step explanation:
The given equation is formed by different variables, where indicates the period of time in years where the rate of inflation is calculated.
In this case, we have a period from 1980 to 2011. The difference between these years would be the period of time used to find the inflation rate.
Therefore, the value of is 31 years.

Answer:
1. Not proportional
2. Proportional
3. Proportional
4. Not proportional
Step-by-step explanation:
A trick I used was to divide 3 by 7 and I got around 0.42.
Then I proceeded to type the fractions into the calculator to see which ones gave me 0.42.
Example: 12 divided by 28 is equal to about 0.42 so it is <u>proportional</u>
24 divided by 54 is not 0.42 so it is <u>not proportional</u>
Answer:
a) The domain is the set of the possible values of x.
In the graph, we can see that x goes from - 4 to 4
So the domain is: D = x∈ {-4, 4)
b) The zeros are the points where the graph cuts the x-axis.
Those values are:
x = -2
x = 0
x = 2.
c) The graph is positive if it is above the x-axis and it is negative if it is below the x-axis.
in the interval {-4,0} the graph is bellow the x-axis, so in this interval the function is negative.
in the interval {0, 2} the graph is above the x-axis, so in this interval the function is positive.
in the interval {2, 4} the graph is bellow the x-axis, so in this interval the function is negative.
