Question

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

Answer 1

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

$x^{2} +2, 0\leq x$

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

$\frac{1}{2} x+5, x\geq 2$

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