1 of 2 a key Date: Period: Review End of Unit 1 Review- Limits and Continuity Lessons 1.10 through 1.16. Reviews do NOT cover all material from the lessons but will hopefully remind you of key points. To be prepared, you should review all packets from Unit 1 (including the Mid-Unit Review). 1. If f (x) = =identify the type of each discontinuity and where it is located. ( x 43 ) ( x -5 ) hole at X= - 3 V.A. at X= 5 State whether the function is continuous at the given x values. Justify your answers! cos(3x), x 1 X>1 5. If the function f is continuous for all real numbers and if f(x) = forte when x *-2, then f (-2) = (xx2) (x +4) - 2+4 2 6. Let f be the function defined by f (x) = x+6 x+8x+12, x # -6 For what value of b is f continuous at x = -6? ( * + 6) (*+2) b , * =-6 (- 6) +2 = 6 X+2=b -4 = 6
