Question

Show that f is continuous on the given interval.
f(x)=sqrt(x-4) [4,8]

Answer 1

what do u think?

Answer 2

I'm probably missing a theorem? Clearly f is continuous at x=c if lim x->c f(x)=f(c)...

Answer 3

oh maybe the epsilon delta definition would work

Answer 4

:-) right

Answer 5

\[f(x)=\sqrt{x-4} \]is there any number in [4,8] that u cant plug in the function?

Answer 6

no everything works

Answer 7

i don't see where you are going with your question as f is defined for every number in the interval
