Question
Graph each function and give its domain and range. See Example 7.$$f(x)=\sqrt{x-5}$$
Step 1
The function $f(x)=\sqrt{x-5}$ is a square root function, which is a type of radical function. The square root function is only defined for $x \geq 5$, because we cannot take the square root of a negative number in the real number system. Show more…
