Note that none of the descriptions of the functions is valid; specifying a range of values as "0≤ x ≥ 2" is meaningless. I will assume that in each example the intended range is like "0≤ x ≤ 2"

1.  on [-3,0);
    on [0,2]

For negative values of x, . On the interval [-3,0), neither x nor -x has the value 0; there are no x- or y-intercepts on that part of the
graph.

For non-negative values of x, on the interval [0,2] both the x and y values are 0 only at x=0. The x- and y-intercepts are both (0,0).

2.  on [-3,0);
    on [0,4]

On the interval [-3,0), x is always negative, so y=2x is always negative; there are no x- or y-intercepts on that part of the graph.

On the interval [0,4], x is clearly 0 at x=0; y is always 1, so it is never 0. This function has an x-intercept at (0,1) and no y-intercept.

3.  on [0,5);
    on [-2,2]

This definition is not valid; the definition results in two different values on the interval [0,2].
