Answer:

[2, ∞)

Explanation:

None of the expressions will yield a number less than 2 using the domain of xs stated.

3, x<0

All numbers less than 0 would lead to the range being 3

$x^(2) +2, 0\leq x<2$

If we use 0, range= 2 (because (0)^2+2=2) and x=1 would yield range = 3

$(1)/(2) x+5, x\geq 2$

Using 2 for x, we get range=6 and the numbers keep going till infinity
