A strictly increasing function is a type of mathematical function where, for any two inputs, if the first input is less than the second, then the output of the first input is less than the output of the second. This means that as you move from left to right along the graph of the function, the values continue to rise without ever flattening out or decreasing. Such functions have unique properties that distinguish them from other types, making them significant in understanding concepts like monotonicity and continuity.
congrats on reading the definition of strictly increasing function. now let's actually learn it.
