Answer:
Explanation:
Let:
We need to know for which value of 
the function 
is equal to 
:
Therefore, we need to solve for the previous equation for :
Replacing the values of and :
Subtract 4 from both sides:
Multiply both sides by -1
Divide both sides by 3:
Therefore the value of for which is 
.
Verify the result:
