For point P(a,b,c)
a is along the x-axis, so does not change the distance from the x-axis.
b and c are both the distance from the x-axis.
Therefore, by the Pythagoras theorem, the
distance from P to the x-axis =
a is along the x-axis, so does not change the distance from the x-axis.
b and c are both the distance from the x-axis.

The function which is used to represent the graphed geometric sequence is
Let a be first term and r common ratio of the Geometric progression.
The Geometric sequence is of the form a,ar,ar^2, ...
The common ratio will be ar/a.
From the graph, we can find out the sequence as 80,20,5, ...
Here we can see that the sequence is in Geometric Progression.
First term a=80
Common ratio r= ar/a
= 20/80
=1/4
General term of Geometric sequence is
Substituting the value a = 80 and r = 1/4,
we get,
Hence, the correct answer is
