Find the values of a and b that make f continuous everywhere.
I see a polynomial. should I factor it? I kinda want to factor it haha.
anyway, I know I gotta focus on x=3. If I can get the two points to be continuous there, I should be good, right?

Hello,
There's no need to factor the polynomial (the second one ).
You gotta focus on x=3 but also on x=1 !
And yes, it should be good.

A function is continuous at x=a if :
So for example at x=1 :
and
Same for x=3, see what expression it is if x<3 and if x>3
