Determine the domain of the function. f(x)= square root of 2-x a: x ≤ 2 b: all real numbers c: x > 2 d: all real numbers except 2

[-∞, 2) so that 2 - x is either zero or positive

Step-by-step explanation:

First look at the function y = √x.  Its domain is [0, ∞ ).

The domain of √(2 - x) is the set of all real numbers for which 2 - x is 0 or +, and that domain is [-∞, 2).

4 and 5)16.97 or 12√2

6)15.59 or 9√3

7)y = 15.59 or 9√3     x =27

8)17.80
