Hello there:

Can anybody help me Graph and find the Domain and Range of these:

f(x) = [x + 1/2] what is the graph of this step function

g(x)= 2 - x

please help me

is [x+1/2] the nearest integer function?

The domain of the floor function is all real numbers, and the range will only be the set of integers.

In order to graph the function, remember that if is the floor function, then for for the integer portion of x and the decimal portion of x, . - August 4th 2010, 11:45 AMrcs

i gues i have found the answer :)

g(x) = 2 – x f(x)

g(x) = 2 – xn where, n≤x<n+1

if

n = 2 2 -2x , 2≤x<3

n = 1 2 –x , 1≤x<2

n = 0 2 , 0≤x<1

n = -1 2 + x , -1≤x<0

n = -2 2 +2x , -2≤x<-1

i could hardly paste or show to you the illustration of this function... i have the image of the graph but i dnt knw how to upload here
