Which graph represents the function of the interval [-3,3]
f(x)= [x]-2

Shown below

In mathematics, the most famous of the step functions is the greatest integer function and this is denoted by the parent function:

We can write some properties of this function as follows:

The function represents the parent function shifted 2 units downward. Therefore, the correct option has been chosen in the attached figure.

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
