MAC 2311 Learning Activity #1 Intro to Limits Names: Arriba Muaydas Group #: 1. Find the average rate of change of the following functions over the given interval: (a) f(x) = 3x2 - 3.x + 5; [-1, 2] ( b ) 9 (t ) = 3 cos ? (t ) ; [ 0 , 6 ] 2. For the graph of f(x) given below, find the following values, if they exist. If it does not exist, state "DNE". (a) f (-1) (d) lim f(x) (g) lim f(x) x-7-4- (b) lim f(ac) (e) lim f(ac) (h) lim f(x) x -+4- ( c ) f (4) (f) lim f (a) (i) lim f(x) x - -5
