Because the function f(x) =-2+√x+7 has √x, x should be more or equal 0.
Domain is x≥0, or [0,+∞).
The smallest value of x=0, so the smallest value of f(x) is f(0) =-2+√0+7=5,
so range is f(x)≥5, or [5, +∞).
Simplify using only positive exponents.

Using scale concepts, it is found that the length of her office is of 10 ft, while the width is of 5 ft.
------------------------
- The scale of 6 cm to 15 ft means that each <u>6 cm in the drawing represent 15 ft in actual dimensions</u>.
- From this, a rule of three is applied to find the dimensions.
First, we find the actual length:
6 cm - 15 ft
4 cm - x ft
The actual length is of 10 ft.
Then, we find the actual width:
6 cm - 15 ft
2 cm - x ft
The actual width is of 5 ft.
