You watch how log stays under linear for most sizes. I point this out because the gap widens fast once inputs stretch bigger. Constant stays way below everything else no matter what. But linear shoots past log like it owns the road. Perhaps you notice exponential ones explode after a while. They leave all the slower ones in the dust right quick.
Now linear edges out log without much fuss at all. I know you compare them by checking points far out on the scale. Log curves twist gently while linear ones cut straight through. Exponential ones balloon out of control suddenly. They overtake quadratic ones later on when things get extreme. Quadratic curves bend up harder than linear yet slower than exponential.
You find n log n sitting between linear and quadratic in the race. I see it grow faster than plain linear but not by leaps. The difference shows up when you plot bigger and bigger inputs. Exponential functions charge ahead of all these eventually. They double or more with each step and that adds up crazy. Factorial ones top them all by growing insanely quick.
But you compare them by imagining the lines crossing at points. I tell you constant never moves while others do their thing. Log inches forward enough to beat constant yet loses to linear. Linear holds its own until quadratic bends steeper. Then quadratic gets passed by exponential which flies off the chart.
Perhaps you sketch this mentally and see the order hold for large cases. I always remind myself small inputs trick you with close lines. Exponential looks tame early but then it dominates everything. Linear and n log n stay close for a bit before separating. Quadratic trails exponential but beats the lower ones handily.
You notice how these paths never really meet again after crossing. I watch the exponential surge while others lag behind steadily. Constant remains flat as a board throughout the whole view. Log inches along but gets swamped by anything linear or more. Then quadratic starts its climb and leaves linear in its wake.
Exponential ones keep multiplying their lead without pause or mercy. I know you see factorial ones as the real monsters here. They multiply all prior numbers and that makes them tower over exponential. Yet in practice we hit those huge ones less often than the rest. Linear and log show up in many everyday routines you deal with.
But exponential pops up in brute force searches that eat time quick. I point these differences out so you pick better approaches later. The graph shows constant at the bottom flat as can be. Log follows with its gentle bend that fools you at first glance. Linear takes over next with its even rise that feels reliable.
Quadratic bends more and passes linear when inputs double often. Then exponential blasts past quadratic like nothing can stop it. You compare by scaling the axis wider each time you look. I find the crossings happen at different spots depending on the functions. N log n threads between linear and quadratic without much drama.
Factorial ones stay highest and grow without any real limit in sight. Perhaps you test this by thinking of bigger numbers each round. I see the slower ones stay useful for their spots in code. Exponential ones demand caution because they balloon so fast on you. Linear stays predictable and that helps when you plan ahead.
Quadratic demands care too since it bends up sooner than you expect. But log keeps things manageable even as sizes increase a ton. Constant wins for speed when nothing changes with input at all. You draw these by hand sometimes to feel how they separate. I do the same and notice the patterns stick in mind better.
Exponential curves twist sharply upward after their slow start. Then they leave quadratic and all below far behind in seconds. Factorial follows an even steeper path that shocks you quick. Linear holds steady but gets outrun by anything quadratic or higher. Log creeps below it all yet above the flat constant line.
You see why some routines slow down on large data sets now. I share this because it helps you choose smarter each project. The order stays the same once inputs pass certain thresholds. Constant leads in speed followed by log then linear and so on. Exponential and factorial trail at the bottom for performance reasons.
Quadratic sits in the middle and often needs optimization tricks. But n log n offers a sweet spot many sorts rely on daily. You compare growth by checking how much each adds per step. I find visual plots make the gaps clear without any doubt. Exponential multiplies its own value repeatedly which speeds it up.
Factorial multiplies even more layers and that pushes it highest. Linear adds the same amount each time which keeps it even. Log adds less and less as it moves along the line. Constant adds nothing at all and stays put forever.
