+2448 My problem is...
I understand what to do but at the same time I don't.
Please explain each one of the problems :)
+118673 Please no one else butt in because I actually want to help RB to understand.
Hi RB,
I like the way tyou said that.
I often say, I understand ... but ... I don't really understand.
There are different levels of understanding in mathematics.
Let's see if I can help.
I'll do the first one and then you can try the others.
1) \(f(x)=2x-5\qquad find\;\;\quad f(6) \quad and \quad f(1)\)
For f(6) you are replacing all the x'es with 6
so
\(f(6) = 2*6 - 5 = 12-5 = 7\)
-------------
For f(1) you are replacing all the x'es with 1
so
\(f(6) = 2*1 - 5 = 2-5 = -3\)
NOW you have a go at at least one of the other questions. show me your working, and I will see if I can help you get to the point of REALLY understanding 
+112 This must be imaginary understanding. Like imaginary numbers, it seems real but it’s not.
+112 I understand, but at the same time, I don’t really understand.
You must be imagining things
+2489 If I square my imagination, then it becomes real:
(You BUTTED in on Melody’s post!)2
+112 Cool! I get three points for butting in.
Maybe I should log in to claim my copyright and points.
+118673 LOL That is a lot of butting in
Do I have to demerit myself as well since I butted in too ?
RP does not seem to need our help anyway she nearly always say she is desperate for help and then works it out within minutes by herself.
This forum must teach by osmosis LOL
+112 RP’s desperation is an imaginary misunderstanding. Like the child who panics because she thinks she’s drowning, but the water is only three feet deep, so all she has to do is stand up.
+118673 Did you actually read any of what we wrote?
My answer came in one minute after yours. I was working on it before you said you could do it.
You had not said that you already understood otherwise I would not have wasted my time.
You have done this too many times RP.
Do not ask questions until you have given youself lots of time to think about it first. !!
If you do not need to ask then do not ask.
If anyone puts their time into giving you an answer then ALWAYS give feedback and say thank you.
+2448 Sorry, I didn't realize. Thanks for helping :)
In return, I'll do one of the problems up there.
3- g(3)=3^2-7(3)+1
=9-21+1
=-11
