This math topic focuses on determining the domain of functions represented by fractions where the denominator includes a linear expression. The problems involve identifying which number line correctly represents the domain of given fractional functions, where the domain is based on values of x for which the function is defined (typically excluding points where the denominator would be zero). This involves understanding and visualizing function behaviors and restrictions graphically on number lines. This is part of a broader unit on solving for domains and ranges of functions.
