Use graphing technology to find the domain of the function f, of, x, equals, square root of, x, plus, 2, end square root, plus, 2, .f(x)=

x+2

+2.

1 answer

To find the domain of the function f(x)=x+2+2, we need to determine the values of x for which the function is defined.

The square root function x+2 is defined only when the expression inside the square root is non-negative. Therefore, we need:

x+20

Solving this inequality:

x2

Thus, the domain of the function f(x)=x+2+2 is all values of x greater than or equal to 2. In interval notation, the domain is:

[2,)

Summary

The domain of the function f(x)=x+2+2 is [2,).
