Rational zeros are everywhere you just have to look on the grid sheet. Then you draw 4 corners . There! You have a rational zero!
The domain of a rational function is the whole of the real numbers except those points where the denominator of the rational function, simplified if possible, is zero.

All integers are rational numbers.

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.
Yes.
The domain of a rational function is the whole of the real numbers except those points where the denominator of the rational function, simplified if possible, is zero.
To find the number of real zeros of a function, you can use the Intermediate Value Theorem and graphing techniques to approximate the number of times the function crosses the x-axis. Additionally, you can apply Descartes' Rule of Signs or the Rational Root Theorem to analyze the possible real zeros based on the coefficients of the polynomial function.

If the number can be expressed as a ratio of two integer (the second not zero) then the number is rational. However, it is not always a simple matter to prove that if you cannot find such a representation, then the number is not rational: it is possible that you have not looked hard enough!
Rational zero test cannot be used to find irrational roots as well as rational roots.
people find me rational at specific times
