Determine the domain of the function. f as a function of x is equal to the square root of seven plus x. x ≥ 0 all real numbers x ≥ -7 x > 0

Option C,  x ≥ -7

Step-by-step explanation:

The given function is f(x) =

Then we have to find the domain of the given function

The given function is defined only when ( x+7 ) ≥ 0

or ( x + 7 ) - 7 ≥ 0 - 7

x ≥ ( -7 )

Therefore, domain of the function will be x ≥ -7

Option C is the answer.

1.3

step-by-step explanation:

3x2=6   9x+6

bring down the 6 on both sides

6+6=12

12= 9x

divide by 9

12/9 =
