    I have a Casio fx-9750G PLUS graphical calculator and I'm trying to use it to save a lot of time in Numerical Methods (MEI) questions. For example, when using the method of bisection I want to be able to just store a function (e.g. f1: x²+2x+5) and then later put in f1(3) to give me an immediate answer as it would save a lot of time. I've looked at the manual (so no-one can reply "RTFM!!!!!11" ) and can't seem to find out how to do this; is it possible?

    Can the calculator work with vectors? Can you write programs in it?

    You can write programs in it, but I don't think it can work with vectors (unless you mean column vectors, then it can handle 3x1 and 2x1 and other matrices).

    Then just write a program which takes an input x, calculates f = f(x) for some given f, and outputs f(x).

    Alternatively, just write a program with a 'for' loop that takes a, say, 10x1 vector V, and sets v(i) = f(i) for x = 1,..,10. Then a reference to the coordinate of the vector will get you what you need. i.e. v(3) will give you f(3).
