Answer:
Step-by-step explanation:
Given this function:
We need to find the value of:
This is really simple because the problem give us the following data:
Using this data we can write a 2x2 system of equations like this:
Let:
and
Our system will be:
We can solve this system using different methods, however I will use elimination method because I believe it is really simple. So:
Replacing into (1)
Now we found the values of and
, our function is given by:
Let's verify it:
As you can see the function satisfies the data provided by the problem. So we can conclude that it is correct.
Finally, let's find for
:
Hence:
