I have an assignment to do in maths and I've encountered some problems. The teacher I have is not very helpful so I hope that I'll receive some help from here instead. Basically, we have to design a function to fit these variables:
x 1.7 2.0 2.9 4.1 5.6 6.3 7.0 8.0 10.0 13.9
y 42.0 21.0 10.3 6.8 5.1 4.8 4.4 4.1 3.7 3.2
First I thought of using a simultaneous equation to solve for a and c by using this formula: y = a(1/x)+c... but it ended up weird and I'm not sure of what x and y variables to use... I'm not even sure of the formula I came up with. So, well, what to do? I know that many possible ways can be used to create an appropriate graph to fit the variables and one of them is supposed to be by simultaneous equations which I personally prefer as I cannot handle complex maths. Guided help would be kind as I am to describe the process and such.
Thank you! (:
