To solve this problem, we have to study the given table carefully. It shows a function and to find the x value, simply look at the given y value and vise versa.
The first question given is to find f(6)
Go through the table at the point where x = 6, look down and you'll find the corresponding value of y
In this case, we have the y value as 59
[tex]f(6)=59[/tex]The second question requests that we solve for x when y = 3
[tex]f(x)=3[/tex]This time, go through the table again but at the y-column or axis, and look at the corresponding x value
We can see that when y = 3, x = 5
The most reliable way to solve this kind of problem is to establish the function itself and you can whatever you want from there.
