## Continuous and discontinuous functions

f ( x) = x 2 + 2 x − 15 x 2 − 2 x − 3. Step 1. Evaluate f ( 3) f ( 3) = ( 3) 2 + 2 ( 3) − 15 ( 3) 2 − 2 ( 3) − 3 = 9 + 6 − 15 9 − 6 − 3 = 0 0. The function is undefined at x = 3, so there is a discontinuity at

## How to Determine Whether a Function Is Discontinuous

## Continuous and Discontinuous Functions

If you look at the function algebraically, it factors to this: Nothing cancels, but you can still plug in 4 to get. which is 8. Both sides of the equation are 8, so f (x) is continuous at x
