Question

lim x>4- ([[x]]-7)

Answer 1

\[\lim_{x \rightarrow 4-} ([[x]] -7)\]

Answer 2

greatest integer function, it will be a horizontal line from (3<=x<4)

Answer 3

yea i have seen graphs of these functions

Answer 4

looks sorta like steps

Answer 5

yes

Answer 6

but i have no idea how to graph one myself

Answer 7

i am assuming if I graphed this I could see the limit

Answer 8

which according to the book is 8

Answer 9

You're approaching x=4 from the left, correct?

Answer 10

they need a grapher on this site

Answer 11

yes from the left

Answer 12

If you're approaching 4 from the left, [[x]] will be 3

Answer 13

so how to i determine the points i need to plot on [[x]]-7

Answer 14

you have to take into account the -7

Answer 15

yes, so -4 overall

Answer 16

It's just the graph of f(x)=[[x]] shifted down 7 units

Answer 17

well the book says 8 so .... >.<

Answer 18

oh i know why

Answer 19

i missed a 5 lol

Answer 20

5[[x]]-7

Answer 21

so to graph this

Answer 22

yes, so 5(3)-7=8

Answer 23

If you were approaching from the right, [[x]] would be 4

Answer 24

yes i understnad that

Answer 25

so you don't know how to graph the greatest integer function?

Answer 26

nope i dont

Answer 27

i know what they look like

Answer 28

but not how to graph one given an equation
