Answer:
Step-by-step explanation:
The general equation of a sphere is as follows:
In which the center is , and r is the radius.
In this problem, we have that:
So
through the point (4,3,-1)
This leads us to find the radius.
So the equation of the sphere is:
Rewrite the inequality without the absolute value
-18 < x - 13 < 18
Add 13 to the whole equation
-18 + 13 < x < 18 + 13
Simplify
<u>-5 < x < 31</u>
