Find the domain of
f(x) = - squareroot x^2 - 4

d. x ≥ 2 or x ≤ -2

Step-by-step explanation:

The domain is the set of all possible x-values that will make the function work.

For the function to work, the radicand cannot be negative.

x² - 4 ≥ 0

x² ≥ 4

x ≥ 2    -x ≥ 2

            x ≤ -2

The domain is x ≥ 2 and x ≤ -2.

The graph of your function shows that ƒ(x) does not exist when -2 < x < 2.

fa tha first one you gonna add y to both sides

it look like this

x-y+y=6+y

x=y+6

therefore your answer is

x =y+6

fa tha second one

you gonna flip tha equation

it gonna look like x-4y=y

then add 4 to both sides

it gonna look like tha

x-4 +4 =y +4

so therefore tha answer is x=y+4
