# Math Help - Continuity 3

1. ## Continuity 3

For what value of the constant is the function continuous on where

2. ## Re: Continuity 3

The answer here is 3 right? 18/6 = 3

3. ## Re: Continuity 3

the left-hand limit lim y-->5- f(y) is 25 - c.

the right-hand limit lim y-->5+ f(y) is 5c + 7.

continuity at 5, means these must be equal:

25 - c = 5c + 7
18 = 6c
c = 3

so, yes.
