What kind of mathematical sentences express at least and at most questions about linear functions?

At least and at most questions about linear functions can be expressed using inequalities. For example, an "at least" question could be formulated as ( f(x) \geq k ), indicating that the function's output is greater than or equal to a certain value ( k ). Conversely, an "at most" question can be expressed as ( f(x) \leq m ), meaning the function's output does not exceed a specified value ( m ). These inequalities help define the constraints on the linear function's behavior.
