The Purplemath Forums

Greetings, I'm having some problems, obviously, with some of my math work. There's a few different ones so hopefully this will all make sense... Any help would be appreciated. 1. Evaluate the function for the given values: f(x) = 5 -3x; x = -4, 2 I'm not sure where to go with that one. I'd a...

A little late, but thank you for your assistance.
This is the first time I've been able to post on this forum since I posted the original message. It's been acting up on me...

Greetings, It seems I'm finally able to post on this forum again... For the past couple weeks it's been giving me an error message every time I try to post. Well, anyway, I'm back with a few more questions on my current math assignment. I don't know if it makes any difference, but here are some of t...

Greetings, Hello again. I've got a few more questions this week. I've got another worksheet of problems and I need to graph them, however with these types of problems I'm not really sure how to convert the answers into something I can graph. I'm also not too sure about the f(x) thing, which I'm not ...

Alright, so I'm just trying to make sure I understand the f(x) thing, with graphing it, too. So for a problem with f(x) I'd just substitute f(x) with three different numbers and solve the problem? Here's an example, so I can see if I'm understanding it... f(x)=x^2-6x+4 X=1, 2, 3 1=1^2-6(...

Greetings, I hope that this is the correct place to put these questions. I can't really find any section of the forum that would particularly fit this... Anyhow, I'm currently in a college math class (MTH-105) where we basically just go over the history of math and mathematicians, and don't usually ...

Thank you for your help. You've actually been the kindest and most understanding person in the few places I posted my questions. The other two forums just basically insulted me for not being able to solve the problems myself. What method(s) did they give you for finding the value of e ? (If none, th...
