√(49-x^2).range,increasing, decreasing and zeros of the function.
------
------
Range: 0<= y <=7
Increasing on (-7,0)
Decreasing on (0,7)
---
Zeros: x = -7 and x = 7.

Let y = , then after squaring both side we have
(1) or
(2) which is the equation for a circle centered at the origin (0,0) with a radius of 7.
The roots are at x = {-7,7}
The range is y = (-7,7)
Since it is a circle, I don't think the other attributes apply.
