Question

The points `(0,3),(2,-1),(4,-2)" and(-1,-1)` represent discreet or continuous data?

Answer 1

It is discrete.

Explanation:

The points described `(0,3),(2,-1),(4,-2)" and(-1,-1)` represent `(x,f(x))` i.e. `x`-coordinate indicates the values `x` takes and `y`-coordinate indicates the value of function `f(x)`.

As `f(x)` is defined just for `x=-1,0,2" and "4` i.e. in other words only for these discreet values of `x`. This represents domain of `x` and `f(x)` represents range.

Hence, it is discrete.
