2.3 Continuity Goal: Find continuity at a point. Find continuous functions. Find Composites. Use the intermediate value theorem (IVT)
Definition of Continuous Functions Continuous functions are used to describe how a body moves through space and how speed of a chemical reaction changes with time. Any function y=f(x)whose graph is continuous when graph can be sketched without lifting your pencil
Where is the graph continuous and discontinuous a)Where is f(x) continuous b)Is it continuous at x=0, and x=6 c)Where is f(x)discontinuous d)What kind of discontinuity Yes (0,1)(6,-4) At x=2 e) 0 4.84 DNE Jump
Intermediate Value Theorem (IVT) In a continuous graph,
Show there is a solution A number is exactly one less that its cube A solution is determined by f(x)=0
Types of discontinuity Removable Removable Jump Infinite
Composition If the function is continuous then all rules apply for sum, difference, product, quotient, and multiples. Hint let u=substitution
