What is the range of f(x) in interval notation?

Answer:
[2, ∞)
Step-by-step 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
[tex]x^{2} +2, 0\leq x<2[/tex]
If we use 0, range= 2 (because (0)^2+2=2) and x=1 would yield range = 3
[tex]\frac{1}{2} x+5, x\geq 2[/tex]
Using 2 for x, we get range=6 and the numbers keep going till infinity
