Answer : f(x)=4[x-3]+2 discontinuous in all integers

f(x) is a floor function

Floor function gives the greatest integer < = given nnumber. Floor function always gives the greatest integer output.

For example , floor (2.25) = 2

2 is the greatest integer less than or equal to 2.25

f(x)=4[x-3]+2

When x= 1, then y = 4(-2) +2 = -6

When x= 1.5, then y= 4(-2) +2 = -6 [floor (1.5-3) = floor (-1.5) = -2]

When x= 2, then y= 4(-1) +2 = -2

When x= 2.5, then y= 4(-1) +2 = -2 [floor (2.5-3) = floor (-0.5) = -1]

When x= 3, then y= 4(0) +2 = 2

When x= 3.5, then y= 4(0) +2 = 2 [floor (3.5-3) = floor (0) = 0 ]

We can see that the y value changes for every integer like x=1, 2, 3 and so on

So answer is all integers.

Likurg_2 [28]

Answer:

  242/27

Step-by-step explanation:

Using the formula for the sum, you can fill in the given values and do the arithmetic.

  Sn = a1·(r^n -1)/(r -1)

  S5 = 6·((1/3)^5 -1)/(1/3 -1) = 6(-242/243)/(-2/3) = 6·(121/81)

  S5 = 242/27

_____

Or, you can write the terms and add them up. The sum is ...

  6 + 2 + 2/3 + 2/9 + 2/27 = (162 +54 +18 +6 +2)/27 = 242/27

You conduct a quality check after running 350 parts 49 of the parts do not need this specifications what percent of the parts do
zepelin [54]

Answer:

14%

Step-by-step explanation:

<em><u>49 parts of 350 parts</u></em> do not need specifications...

= 49/350

So, 49/350 = x/100

= <u>49(100) = 350x</u>

= 4900 = 350x

= 4900/350 = x

x = 14%
