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

answer:   b

step-by-step explanation:

x2 = 16

x can not be a negative number because 16 is positive

the only answer would be positive 8
