I believe this is a ceiling function but I haven't ever used one and was wondering how to solve this type of problem? Please just explain what they do/work and how to solve a ceiling function

xxxxxxxxxx

This should help:

floor function: floor(x) is the greatest integer less than or equal to x. e.g. floor(3.4) = 3

ceiling function: ceil(x) is the smallest integer greater than or equal to x. e.g. ceil(3.4) = 4

We can solve this

(x + 3) = 10 ( x - 1) + 4

x - 1 = 10 (x - 1)

10 (x - 1) - 1(x - 1) = 0

9 ( x - 1) = 0

x = 1 = the floor

This means that any x on the interval [ 1, 2) will solve this equation

Thanks, CPhill!!!
