The problem gives you two values for the function f(x) at two different x-values. (Different students will get different numbers.)

This is OK, you will have to find f(x) by integrating twice and it will have two constants of integration in it. You can then use the two values of f , one at a time, to find the two constants. Hint: Use f(0) first!

If that’s not enough of a hint you can post a question over on Piazza. Don’t forget to tell us exactly what your problem said, as everyone gets a different version of the problem!
