Justification with the intermediate value theorem: equation
The IVT only can be used when we know the function is continuous. If you are climbing a mountain, you know you must walk past the middle in order to get there, no matter how many turns you take along …

Intermediate value theorem (IVT) review (article) | Khan Academy
If we have a function f (x) defined on an interval (a,b), if both lim (x->a+) f (x) and lim (x->b-) f (x) exist, then we should be able to make some conclusions about IVT being valid. Essentially, we're just …

Conditions for IVT and EVT: graph - Khan Academy
Analyzing graphs at certain intervals to see if the intermediate value theorem or the extreme value theorem apply there.
Justification with the intermediate value theorem: table
𝑓 (𝑥) = 0 could have a solution between 𝑥 = 4 and 𝑥 = 6, but we can't use the IVT to say that it definitely has a solution there.
Intermediate value theorem (video) | Khan Academy
It was first proved by Bernard Bolzano, and there is in fact a slightly different formulation of IVT that is called Bolzano's theorem. That version states that if a continuous function is positive somewhere and …

Worked example: using the intermediate value theorem
Actually, it is very possible for the function to exceed those values in either direction, especially beyond the concerned interval. The IVT only tells us that for this case, every value between 3 and 6 is …
