Question

What is the range of the function

f(x) equals X squared +2?
All real numbers
All real numbers greater than two
all Real numbers greater than or equal to two
or all real numbers less than or equal to two

Answer 1

All real numbers Greater than or equal to 2.

Explanation:

If x has a nonzero valve either positive or negative its square is always positive so we have a number greater than 2.

and if x has value 0 than its square is zero and we get 0 plus 2 equal to 2.

Hence answer is

All real numbers Greater than or equal to 2
