Question

find each function value, if it exists.... \[f(t)=\sqrt{t^2+1}\]

Answer 1

You set it greater than or equal to 0 and solve for t
t^2+1ge0
t^2 greater than or equal to -1
tge1

Answer 2

and then you probably write (-infinity,-1)U(1,infinity)

Answer 3

i dont get how im suppose to write in the answer

Answer 4

it has f(0)=......
and im suppose to fill it in

Answer 5

I assume it wants you to plug in 0 and sovle...

Answer 6

so wat am i suppose to do?

Answer 7

\[\sqrt{0^2+1}\]
