Given:
The graph of an invertible function 
<em> </em>is given.
To find:
The value of 
.
Solution:
We know that, if the graph of an invertible function passes through the point (a,b), then the inverse function 
passes through the point (b,a).
From the given graph it is clear that the graph of the function passes through the points 
.
So, the inverse function must be passes through the point 
.
Therefore, the value of inverse function is 
at 
. So, the value of is .
Answer: the cost of an adult ticket is $9.
The cost of a child's ticket is $13
Step-by-step explanation:
Let x represent the price of one adult ticket.
Let y represent the price of one student ticket.
On the first day of ticket sales, the school sold two adult tickets and three students tickets for a total of $57. It means that
2x + 3y = 57- - - - - - - - - -1
The school took and $70 on the second day by selling two adult tickets and four student tickets. It means that
2x + 4y = 70- - - - - - - - - -2
Subtracting equation 2 from equation 1, it becomes
- y = - 13
y = 13
Substituting y = 13 into equation 1, it becomes
2x + 3 × 13 = 57
2x + 39 = 57
2x = 57 - 39 = 18
x = 18/2
x = 9
9/10is the simplest form
180/200 first we need to cancel only one zero
Then divide it by 2
