The events will have the same attendance whenever the functions intersect.
B
b
Notice that we are given the equations for the functions.
A
a
Approximately in year 2007
B
b
We will substitute x=3 into the equations and see if they are equal. See the solution for the process.
Practice makes perfect
a
To find when the events will have the same attendance, we want to find the x-value when the two functions intersect.
We can see that the functions will intersect around x=3. Note that year 0 corresponds with 2004. This tells us that x=3 is really the year 2007, so in approximately 2007 the attendances should be equal.
b
We can verify this by checking if the functions are actually equal at x=3. Since we are given the equations, we will substitute x=3 into the equations and see if they are equal.
