Using the continuity concept, since the lateral limits and the numeric value of the function are equal at the point in which the definition changes, the function is continuous.
<h3>What is the continuity concept?</h3>A function f(x) is continuous at x = a if it is defined at x = a, and:
The definition of the piecewise function is given by:
- f(x) = 2x - 1, x < 2.
- f(x) = 3x/2, x >= 2.
Since the definition of the function changes at x = 2, and the domain of the function has no restrictions, this is the only point in which there may be a discontinuity.
The lateral limits are:
.
.
The numeric value is:
f(2) = 1.5 x 2 = 3.
Since the lateral limits and the numeric value of the function are equal at the point in which the definition changes, the function is continuous.

Answer:
grains of sand are in the Sahara Desert
Step-by-step explanation:
Given :
The Sahara Desert has an area of approximately 9,400,400 sq.km.
Depth = 150 m
To Find :Approximately how many grains of sand are in the Sahara Desert?
Solution:
Area of Sahara desert = 9,400,400 sq.km.
So,
Volume of sand =
=
So,
1 cubic cm holds grains of sand = 8000
holds grains of sand =
=
Hence grains of sand are in the Sahara Desert
