This lecture covers the concepts of injectivity and surjectivity in functions, using graphical representations to determine if a function is injective or surjective. It explains the criteria for injectivity and surjectivity, showing how horizontal lines intersect the function's graph. The lecture also explores different scenarios where a function can be injective, surjective, or both, providing visual examples to aid in understanding.
