Which graph represents the step function f(x)=⌊x−1⌋ ?

The correct option is fourth.

Explanation:

The given function is a greatest integer function or a step function.

In these type of functions the value of the function is always an integer and it is a piecewise function which is defined as,

In the given function is we have (x-1) instead of x, so we will get,

It means the value of function is the integer n for all the number lies from (n+1) to (n+2), Where (n+2) is not included.

Similarly the value of function from 1 to 2, where 2 is excluded. Therefore the graph 4 represents the graph of the given function.

use the power rule  

( a b ) n = a n b n

to distribute the exponent.

apply the product rule to  

3 x 2 y 3 . ( 3 x 2 ) 2 ( y 3 ) 2

apply the product rule to  

3 x 2 . 3 2 ( x 2 ) 2 ( y 3 ) 2

raise  

3

to the power of  

2 . 9 ( x 2 ) 2 ( y 3 ) 2 multiply the exponents in   ( x 2 ) 2

.

apply the power rule and multiply exponents,  

( a m ) n = a m n . 9 x 2 ⋅ 2 ( y 3 ) 2

multiply  

2   by   2 . 9 x 4 ( y 3 ) 2

multiply the exponents in  

( y 3 ) 2 .

apply the power rule and multiply exponents,  

( a m ) n = a m n . 9 x 4 y 3

⋅

2

multiply  

3   by   2 . 9 x 4 y 6

step-by-step explanation:

it is x equals 3   plese mark me really need it
