For 6(b),

The solution is,

However, for $a = 1$ they could have also said that f is not continuous since f(1) is not defined (vertical asymptote) correct?

Many thanks!

No.

The graph for problem 6. clearly shows that f(1) is defined. It appears to have the same value as f(3).

Do you attempt to do these problems yourself, or do you just look at the solutions? Usually, it seems, you also need help following the given solutions.

Thank you for your reply @PeroK!

I often attempt the problems myself, but I get it wrong and sometimes don't understand the solutions.

Many thanks!
