Answer 1

Answer:

The domain of function f defined by f(x) = √x is the set of all real positive numbers and zero because the square root of negative numbers are not real numbers (think of √ (- 4), is it real?). In inequality form, the domain of f(x) = √x is written as

x ≥ 0

in interval form the domain is given by

[ 0 , + ∞)

Answer 2

=> (-5)-(-48)÷(-16)+(-2)×6

=> -5+48÷-16-2×6

=> -5-3-2×6

=> -5-3-12

=> -20
