Math question

Answer 1

did you graph using desmos?

Answer 2

Yeah it looked closest to A

Answer 3

what did you type into desmos?

Answer 4

I just typed the function. That's what I'm supposed to type, right?

Answer 5

what exactly did you type though?

Answer 6

f(x) = 4[x] + 5

Answer 7

ok so desmos doesnt' know how to handle that

the double bracket notation means "greatest integer" or "floor" function

so instead of typing `[[x]]` you would type `floor(x)`

Answer 8

Ohh so it's D?

Answer 9

can you show me a screenshot of your desmos graph?

Answer 10

zoom in to get a better look

Answer 11

use the mouse wheel to zoom in

Answer 12

Oh so C?

Answer 13

yeah C is the best match. Hopefully you can see it (assuming you zoomed in enough)

Answer 14

Yeah I zoomed in and I realized that it's C. Thanks so much.
