The range of which function includes -4?

Inessa [10]

Start with the last two choices.
You have x + 5 and x - 5 in the square root.
A square root can never be negative.
That means that the lowest value y can have in the last two choices is 0.
The range does not include -4.

Now look at choice B.
sqrt(x) is at least 0.
Then you add 5.
The range does not include -4.

Now look at choice A.
sqrt(x) is at least 0.
Now you subtract 5.
The lowest value y can have is -5. That includes -4.
Choice A is the answer.
y will be at least 5.

Three women, Chantel, Marissa, and Qian, enjoy running laps around a circular track. Each women runs at a constant speed. It tak

It takes 150 seconds for Qian to complete the track.

Let she runs the track in the clockwise direction.

In 60 seconds, she runs $\frac{60}{150}$ = $\frac{2}{5}$ th of the track.

Since she meets Marissa, who is running in the opposite (counter clockwise) direction in every 60 seconds, Marissa should have completed $\frac{3}{5}$ th of the track.
