50 has no zeros. It's equal to 50 under all conditions.
x3 + x2 - 17x + 15 = (x - 1)(x - 3)(x + 5). Thus, the zeros are 1, 3, and -5. All three zeros are rational.
If leading zeros are allowed, then there are ten thousand possible: 0000 through 9999. If leading zeros are not allowed, then it is 1000 through 9999, eliminating 0000-0999, and now there are nine thousand possibilities.
Not necessarily. The denominator need not have any real zeros, for example x2+1. Not necessarily. The denominator need not have any real zeros, for example x2+1. Not necessarily. The denominator need not have any real zeros, for example x2+1. Not necessarily. The denominator need not have any real zeros, for example x2+1.
No. All whole numbers are integers.

The rational zeros (or rational roots) of a function y = f(x) are the rational values of x for which y is zero. In graphical terms, these are the values at which the graph of y against x crosses (or touches) the x-axis - PROVIDED that the x value for these points are rational. In the simplest cases, you can solve f(x) = 0 algebraically to find the rational zeros. In other cases, you might need to solve f(x) = 0 by graphical methods, by trial and improvement or by numerical methods such as Newton-Raphson. In all these cases, you need to confirm that the x value is rational.

Ok, if the number ends there at the zeros right before the ellipses, then yes that would be a rational number. The whole point of a rational number is that it ends. All whole numbers are rational numbers. It's when you get into the decimals that you have irrational numbers. 1/3 for instance is not a rational number. In decimals it is something like 0.3333333...etc. and never ends. The number listed up there has no decimal, meaning it has to end somewhere.
