This math topic focuses on finding the domain of functions represented by fractions of linear polynomials and mapping this domain to a number line. Each exercise presents a linear fractional function and requires identifying the correct number line graph that represents the function's domain, specifically considering values that would make the function undefined (usually values that would make the denominator zero). The skills practiced include analyzing functions algebraically to determine valid input values and understanding how to represent these values graphically on a number line.
