Well I completely disagree that one needs to have a graph to work this question.
w(x)=\begin{cases}-x^3+1 & x\le 1 \\2|x-1|-2 & 1<x<3\\ (x-5)^2-2 & 3\le x \end{cases}
Look the right column. We have (-\infty, 1]\cup(1,3)\cup [3,\infty)=\Re, the set of real numbers.
That tells us that the set of...
I almost never reply if it requires completing someone else's proof.
But in this case the suggested proof is so ridiculous as to cry out for a correction.
1) \(m(\widehat{AB})=m(\angle AOB)\); the central angle theorem.
2) \(m(\widehat{AB})=2m(\angle ACB)\); the inscribed angle theorem.
3)...
AH! Synthetic Division that is not so fond memory from my childhood.
I don't think that it has crossed my path in at least fifty years.
I thought that had gone the way of finding the square root by hand. Guess not.
Have these math-ed types heard of Computer Algebra Systems?
@Will Red, you are a pitiful TROLL. Anyone who tries to capsulize on our current nation tragedy is truly despicable.
If you can show that you have a PhD/MD is a research area well then O.K., otherwise butt out!
As many of you know that in my former life I read/edited thousands of test questions. But the above question is a complete and utter mystery to me. Mostly I have had some idea, no matter how vague, of what is going on. But not with this one. There are at least two helpers who seem to understand...
There are six sixth roots of -12+5i see here.
See that there are six of them. Each of them is on a circle centered at the origin of radius |-12+5i|^{1/6}=\large\sqrt[6]{13}
However, the salient feature is the fact the the are evenly spaced on the circle and the central angle between any to...
In my experience in courses dealing with functions the notation fg(x) means f(x)\cdot g(x).
Just as f+g(x) means f(x)+g(x) or the addition of functions then fg(x) means multiplication of functions.
In this case fg(x)=gf(x)=3x^3+x^2.
It appears that you are assuming that it is f\circ...
I have no idea what the box method is. But whatever it is, it is useless in factoring.
Having won a citywide factoring contest years ago, I can tell you how to learn factoring.
My algebra teacher then gave me a sheet of four hundred problems.
They all looked like (7x-4)(2x+5). When I objected...
This Question, \large{-2|2t|=-24} is exactly the same as \large{|t|=6}
which is exactly the same as \large{|-4t|=24} which is exactly the same as \large{|2t|=12}.
It is a sad commentary on the state of basic mathematics education if
anyone cannot see the solution of \large{|-4t|=-24} is less...
You don't need either integration or differentiation; just the ability to count and estimate.
How many square units are shaded in? This is a standard exercise in beginning calculus. The whole idea is to get students to realize what the course is all about. Many who have taught calculus do not...
