There used to be a time when those were the only ways out. But thanks to technology now, we have something known as the Algebrator! It’s quite easy to use, something which even a total newbie would enjoy working on and what’s even better is that it would solve all your questions and also explain the steps it took to reach that answer! Isn’t that fabulous? Well I think it is, and I’m sure after using it trying it, you won’t disagree with me .

1.Hey mate, you are on the mark about Algebrator! It is absolutely fab! I downloaded it recently from https://mathscitutor.com/multiplying-and-dividing-rational-expressions.html after a magazine suggested it to me. Now, all I do is type in the problem assigned by my teacher and click on Solve. Bingo! I get a step-by-step solution to my math homework. It’s almost like a tutor is explaining it to you. I have been using it for four weeks and so far, haven’t come across any assignment that Algebrator can’t solve. I have learnt so much from it!

I remember having difficulties with y-intercept, function domain and reducing fractions. Algebrator is a truly great piece of math software. I have used it through several algebra classes - Algebra 1, College Algebra and Algebra 2. I would simply type in the problem and by clicking on Solve, step by step solution would appear. The program is highly recommended.

You can download this software from https://mathscitutor.com/determining-if-a-function-has-an-inverse.html. There are some demos available to see if it is really what you are looking for and if you find it useful, you can get a licensed version for a small amount.
