Hey,

Any help on this problem would be appreciated. For some reason I can't for the life of me solve any of these questions when an '=' sign is introduced:

f(x) = {8x + 4 x < or = 9

and f(x) = {-4x + c x > 9

The question is : Find the value of 'c' that makes the function continuous.

Again, any help appreciated,

Craig.
