Given:
Function is:

Find-:
Check for solution
Explanation-:
The value of "y" is:

For (0,8)
Check value of "y" at x = 0 then,

So (0,8) it is not a solution.
Check (3,-7) the value of "x" is 3

So (3,-7) is the solution of function.
Check for (1 , 2) value of "x" is 1.

So, (1,2) is the solution.
Check for (4,-5) the value of "x" is 4.

So, (4,-5) is not a solution
