# Continuous function

## Homework Statement

Determine whether the function is continuous, piecewise continuous or neither on the segment [0, 10] and sketch the graph of f(t).

f(t)= {10-t, 0<=t<=8 and 10, 8<=t<=10)

## The Attempt at a Solution

I would say that it was neither as the right hand limit at t = 8 doesnt equal the left hand limit. But im not sure wat the difference is between a continuous function and a piecewise continuous function???

thanks for any help

You are absolutely right. A piecewise continuous function is continuous on the interior of each of the pieces, a continuous function is continuous everywhere.

No, Dick, NOT "absolutely right". That function is equal to 10- t for $0\le t\le 8$ and 10 for $8\le t\le 10$ so it is continuous on the interior of each of those intervals and is "piecewise continuous", not "neither".
