What is a Piecewise Function? | Precalculus Exercises

What is a piecewise function? Piecewise functions are very cool, and give use a whole new world of functions to investigate and imagine! One of these functions is the absolute value function, which you may very well be familiar with!

Just like the name sounds, a piecewise function is a function that is defined in pieces. There are different rules for different parts of the function's domain. We go over examples, piecewise function notation, and how to graph a piecewise function in this full video math lesson on piecewise functions! #precalculus

3:08 Sir '0' will not be included for the second graph but why did you make an open interval on '3' ? Isn't '3' greater than '0' ?

Hi sir, so are there like two types of piece wise function, one that drawn with lower bound and upper bound lines and another one like this? Also sir what's a min.piecewise function(is that a thing)
Also sir SUPPOSE if i were to design a rollar coaster usiing piecewise funciton, how would I do it

[weareateam]

I wonder when a piecewise function being used?

Thank you for saving my 8th grade grades

There is literally 0 point in these problems. Even in a job I am struggling to find a reason to use these when there’s incredibly more simple ways to do it’s job but better
