Determine whether the given function is rational or polynomial and also find the domain for each of the following function
f(x) =
x
x
2 − x − 2
g(t) = √2t − 1
f(x) =
(x + 2)(x − 1)
(x − 1)
h(x) = {
x + 2 if x ≠ 1
0 if x = 1

step-by-step explanation:

hjkj

about 0.75 hours

step-by-step explanation:

she will sew have sewn five dresses   and be 1/3 done with the sixth one in an hour.

step-by-step explanation:

3/4 of an hour=45 mins

lucy makes 1 dress per 11.25 minutes

45 mins+11.25 mins=56.25 mins

60 mins- 56.25 mins=3.75 mins

3.75 mins is 1/3 of of 11.25 mins

therefore she the other 1/3 would be part of the hour and she will have sewn 5 dresses and begun the sixth.
