It is a function of the variable X.
Or in other words, a function of the variable X is calculated by 3x^2 + 2x - 1.
Alot of times, instead of saying f(x) 'Function of X' people will just use 'y'. Its sort of like saying the word 'skin' in place of 'epidermis'
Hope that clears it up, Cheers !

Yes, it is a function of y = 3x^2+2x-1 against x.

Yes. In math, a function is something where for every input value, there is only one output value. So, for example in the function above if you plug in x=1 you get f(x)=4...and that's the only answer you get. This is true for any value of x, so f(x) is a function.
