Evaluate the following examples of the greatest integer function:
f(3.4) = [[3.4]] =
f(0.8) = [[0.8]] =
f(-1.7) = [[-1.7]] =
f(-3.5) = [[-3.5]] =

Step-by-step explanation:

To evaluate the domains of the greatest integer function, the rule is that you always round DOWN to the next whole number.

f[[3.4]] = 3

f[[.8]] = 0

f[[-1.7]] = -2

f[[-3.5]] = -4

Always round down!! Just remember that and you'll be ok!

First isolate the x. Always remember that the way you do this is the opposite of the what is happening to the number you want to move.
You want to move the -5 from the left side to the right side by doing the opposite and adding it to both sides.

Like: 27x-5=-5+11

27x-5+5=11+5

So 27x=11 Continue to isolate the variable
