What is the domain of the function f(x)=square root of 2-x?

domain : ] -∞ , 2]

Step-by-step explanation:

the value of 2-x must be more than or equal to 0

because you there is no square root for negative number

2-x ≥ 0

x ≤ 2

first one

step-by-step explanation:

3/4 ÷ 3/4

step-by-step explanation:

basically divide any proper fraction with itself to fit the criteria.

so if we are using 3/4, then:

3/4 ÷ 3/4 = 1

so 1 is the quotient.

and the numerators for both these fractions is 3.   and if we divide the numerators:

3 ÷ 3 = 1

we see that quotient is equal to our original quotient as well.
