1. August 31 st By end of class today you should be able to: Know the difference between continuous, discontinuous and discrete functions

2. Continuous Functions… When you do NOT have to pick up your pencil to draw the entire picture.

3. Is this graph continuous?

4. DISCONTINUOUS

5. What about this one? This is called a DISCRETE graph. Any set of points is discrete!

6. A student group is selling chocolate bars for $2 each. The function, f(x) gives the amount of money collected after selling x chocolate bars. DATA: continuous or discrete? Algebraically: y = 2x OR f(x) = 2x

7. A low-flow shower head releases 1.8 gallons of water per minute. The function V(x) gives the volume of water released after x minutes. DATA: continuous or discrete? Algebraically: y = 1.8x OR v(x) = 1.8x
