Activity 1: Continuous or Not Continuous. Part A. Identify the following functions if continuous or not. 1. f (x) = 3x2 -2 4. f ( x) =_ 2. f(x) = 12-25 x+5 5. f (x) = x2-2x+1 3. f (x ) = *2-5x+6 x+2 Part B. Identify the following functions if continuous or not at a certain point or interval. 6. f(x) =-2x41 x-1 at x = 1 9. f ( x ) =+3x+2 * + 2 on [ - 1, 2] 7. f(x) =-7 at x = 2 10. f (x) = Vx2 +2x+ 1 on [ -2,0] 8. f(x) = x +3x -4 on [-5, 2] Activity 2: Solve and Graph! Is the function f(x) = x - x - 6 is continuous on the closed interval [-1, 2]? Show your solution satisfying the 3 conditions and sketch the graph. Analysis: Express what you have learned in this lesson by answering the questions below. 1. How to determine whether the function is continuous or not at a certain point? 2. How to determine whether the function is continuous or not on a closed interval? 3. How to illustrate the continuity or discontinuity of a function
