the linearization of f(x) = x^4 + 3x^2 with a = -1 is L(x) = 4 - 10(x+1) the linearization formula is L(x) = f(a) + f'(a)*(x-a) when, a = -1 f(a) = (-1)^4 + 3(-1)^2 = 4
Yet another way to say this is: “The value of y is a function of our choice for x.” When this statement is written using mathematical symbols, it becomes: y = f(x).
2011/7/15 - In this video I try to explain what a function in maths is. I once asked myself, why keep writing y=f(x) and not just y!?? I've since realised that 'y' ...

So f(x) shows you the function is called "f", and "x" goes in. And you will often ... f( x) = x2 shows you that function "f" takes "x" and squares it. Example: with f(x) ...
