Question

Which value of x is in the domain of f (x) =v x-7?

Answer 1

Answer:

The domain of the function are values of x that respect the following condition: $x \geq 7$

Step-by-step explanation:

We are given the following function:

$f(x) = \sqrt{x - 7}$

Domain of the square root function:

The square root does not exist for negative values, so the domain of a square root function:

$g(x) = \sqrt{h(x)}$

Is $h(x) \geq 0$

In this question:

$f(x) = \sqrt{x - 7}$

Then:

$h(x) = x - 7$

$x - 7 \geq 0$

$x \geq 7$

The domain of the function are values of x that respect the following condition: $x \geq 7$
