Which graph represents the function f(x)=4[x]?

Check the picture below.

bearing in mind that ⌈some expression⌉ means "ceil" or the ceil() function, which means any number in between one integer and the next, "ceils" or gets bumped up to the next integer.

namely for example, for y = ⌈x⌉ will yield

y(0.5) = 1

y(0.7) = 1

y(0.0000001) = 1

y(3.0000001) = 4

y(-2.000001) = -2

y(-5.00001) = -5

and so on

the same is true btw for the y = ⌊x⌋ or the "floor" floor() function, but it "floors" or drops down instead.

y(0.5) = 0

y(3.9999999) = 3

y(-5.0000001) = -6

and so on.

in this case is y = 4⌈x⌉, so any values in between each integer for "x" gets bumped up.

-4

step-by-step explanation:

do 6-10=

if u need it to be negative.
