Let

f(x) = x+ 3 if x > 3

f(x) = x - 6 if -3 <= x <= 3

f(x) = 3x + b if x < -3.

 

Find  a + b if the piecewise function is continuous (which means that its graph can be drawn without lifting your pencil from the paper).

Well for starters,

 

x-6 = 3x+b   when  x=-3

from that you can find b

 

There is no 'a' in those equations ??
