Which of the following statements is true about the greatest integer function? a. the function is defined as the greatest integer greater than or equal to x. b. the greatest integer function is classified as a piecewise function. c. the range of the greatest integer function is the set of natural numbers. d. the domain of the greatest integer function is all whole numbers. 2. what's the common difference of the sequence –5, –2, 1, 4, 7, . . ?

1.B

2.common difference, d=3

Step-by-step explanation:

We are have to find the true statement about the greatest integer function

We know that the greatest integer function is defined as the value less than or equal to x.

A. The function is defined as the greatest integer greater than or equal to x. It is false. By above definition of greatest integer function.Option A is false

B.The greatest  integer function is calssified as a piecewise function .Yes ,w ecan see that from the graph the greatest integer function is a piecewise function. Therefore, it is true.

C.The range of integer function is the set of natural numbers

It is false because the range of integer function is the set of integers.Hence, option C is false.

D. The domain of the greatest integer function is all whole number . It is false because the domain of integer function is set of real numbers not a set of whole number.Hence, option D is false.

2. We are given that a sequence

-5,-2,1,4,7,.....

[tex]d_1=d_2=d_3=d_4=d=3

The difference between any two consecutive terms of a sequence is equal. Hence , the sequence is AP.

The common difference of the AP is 3.

answer

explanation

the area of a circle is calculated using the formula

or

we can use any of the above formulae to calculate the required. preferably, let us use the latter since the diameter is

we substitute the diameter into the formula to get:

this is the exact value for the area of the circle.

the correct answer is a

c
