Question

Which is the graph of y = ⌊x⌋ – 2?

Answer 1

The third graph from left to right

Explanation:

The function
`f(x)=\left [ x \right ]` is called Greatest Integer Function of x is such that it returns the largest integer less than or equal to x

Some examples of points are (0,0),(0.5,0),(1,1),(1.9,1),(-0.7,-1)

Since our function is

`f(x)=\left [ x \right ]-2`

We must subtract 2 to the points above like

(0,-2),(0.5,-2),(1,-1),(1.9,-1),(-0.7,-3)

The only graph that complies with such requirements is the third one
