For what values of the constants b and c is the function f continuous on ( , ), where f ( x ) = cx + b if x ( , 2] b + x if x (2 , 5) cx 2 if x [5 , ) 7. The height (in meters) of a particle moving along a vertical line is given by h ( t ) = 100 t 250, where t is measured in seconds. (a). Find the average velocity of the particle over the time interval [2,5]. (b). Find the instantaneous velocity of the particle when t = 4. 8. Evaluate the limit lim x 1 x 2 + 3 x + 2 x + 1 9. Let f ( x ) = b x + 4 if x 2 2 x 2 + 3 if x >2 Sketch the plot of f ( x ) and determine the following limits, if they exist: (a). lim x 2f ( x ) (b). lim x 2 + f ( x ) (c). lim x 2 f ( x ) 2...
