Ms. R... something with an R. Rietta? Yeh that's the one. Line 1 with rietta. lulz. I already got an answer on another forum but it has like 9 decimal places LOL. I'll have to use that. ;< It's like 12.2203213983x + 52.1092312029^x + ln(x+5) + 44.210931^whatever lol. Eitehr way i;x'm drunk at the moment and have no idea how to do the asisngment LOL! gud luck!

Looks like you and I have the same maths class Lake Tuggers ? Either way, I'm looking for the exact same question. So looks like we won't have unique functions Crozius . For the first, pick the first three values and arbitrarily decide the derivative at the third point should be -1. For the second, start on the other end and match the derivative, since the problem statement says it has to be differentiable everywhere. Really, just pick some functions out of a hat and make them do what you want. The derivative of -1 was 100% arbitrary. The starting place is a function with arbitrary coefficients. Then you solve for the coefficients that make it do what you want.
