This should be a simple question to answer… I’m doing a high school correspondence course, Algebra 2 and I’m trying to understand the “greatest integer function” which apparently has something to do with Step Functions…(adsbygoogle = window.adsbygoogle || []).push({});

They give me very little to go one, a few tables and graphs which don’t mean anything to me.

The problem I’m trying to solve is this:

Evaluate f(3/4) if f(x)=[[1-2x]]

The double brackets are basically what the symbol looks like in my book.

So how do I “Evaluate” it? What in the world do I evaluate? The examples they give me are not in the above questions format, so I can’t draw any parallels to understand what they are doing!

They give me some answers to choose from (multiple choice) and they are just numbers between -2 and 1.

Any help would be appreciated, like maybe a link somewhere I could get a descent explanation of solving problems like the one above.

Here are some screen shots of the two pages in my textbook that talk about step functions, which I have yet to understand how their examples could possibly help answering the problem they gave me.

Thanks,

Alan
