Interactive video lesson plan for: How to make a function continuous (for a piecewise function) (KristaKingMath)

Activity overview:

► My Limits & Continuity course: https://www.kristakingmath.com/limits-and-continuity-course

Oftentimes when you study continuity, you'll be presented with problems in which you're asked to solve for the value of some constant within a piecewise-defined function that will make the value of that function continuous.

Basically what's happening is you're being given equations that define the function on either side of a particular value of x. In other words, they're giving you the left- and right-hand limits. In order for a function to be continuous at a point, the left- and right-hand limits must be equal. So you're trying to solve for the value of the constant that will make the pieces equal to each other and the "break point".

In order to solve a problem like this one, you want to plug in the x-value of the "break point" then take the left-hand limit of the piece that defines the function on the left and the right-hand limit of the piece that defines the function on the right, and then set the resulting pieces equal to one another.

The value you find for the constant is the value that forces the left- and right-hand limits to come together and be equal at the "break point", which would make the general limit exist at that point, and therefore make the function continuous there.

Hi, I’m Krista! I make math courses to keep you from banging your head against the wall. ;)

Math class was always so frustrating for me. I’d go to a class, spend hours on homework, and three days later have an “Ah-ha!” moment about how the problems worked that could have slashed my homework time in half. I’d think, “WHY didn’t my teacher just tell me this in the first place?!”

So I started tutoring to keep other people out of the same aggravating, time-sucking cycle. Since then, I’ve recorded tons of videos and written out cheat-sheet style notes and formula sheets to help every math student—from basic middle school classes to advanced college calculus—figure out what’s going on, understand the important concepts, and pass their classes, once and for all.
