I am failing middle school math.

If you could include a very brief explanation, that would be great. Thanks.

I think that’s how automatic transmissions work

I know how those work. I just don’t know shit about math.

I believe the correct answer is G, assuming the given context is all of the context.

The domain is the set of all numbers that the independent variable, x, can take that then make f(x) a real number. If there was an x in the divisor, or typically, taking a square root of a negative number.

In this case, any value of x you plug in, would give a real value for f(x).

I’m confused how fast was train A going when it left station B ?

Yes.

It is G.

Th e domain is the set of values of x that make the function work.

Because it’s something simple (x^2), all real numbers can be used for x.

The domain, or the set of input values to the function, here is the set of all real numbers. No matter which value you put in, you'll get a result.

I think we were confused because parabola. I think we’ve got it now, Thanks.

IIf u square anything it will be a positive number and then u take that away from 9 so it can never be more than nine.

Yes. Exactly.

Beats the heck out of me. You might as well ask me to administer a NetWare 3.12 server or a Cisco router. I’m amazed at how much stuff I don’t remember how to do. I was a network administrator for years, but it would take me a while to figure it out again. I had lots of math classes, through calculus, but I can’t remember even the most basic stuff these days.

The human brain constantly amazes me with the ability to toss away unused information and reallocate that space to more current data . Too bad we can’t just shove in an bigger SD card and save the old data. But on the bright side, this loss of memories can be a blessing in disguise. It’s said that those with eidetic memories have more problems than those without because they can’t forget the negative things that happened in their past, and those memories remain fresh and raw.

Technically imaginary numbers would work too. Square one and you end up with a negative number.

I’m sure everyone has already answered but since kinja won’t show me their comment, the answer is All Reals . Domain is the input to a function, which is everything. The output is the Range (less than or equal to 9 for this equation unless my brain is not working right).

Tekamul > NYankee1927
09/14/2019 at 19:35

Yes, but multiple choice.

If you haven’t, you should read this article. Touches on memory in the context of languages.

That’s the range, not the domain.

Yes, others have answered it, but thanks for there reply. My son actually had it early on, but we didn’t understand what he was trying to say. He graphed it, and it came up as an inverted parabola. He said that the two arms of the parabola go on to infinity, so there is no “cap” to the possible numbers. The other three possible answers to the question all place a limit on the available numbers.

Smart kid. Middle school or early high school, right? Get him some Martin Gardner puzzle books, like “Aha! I nsight”

One with a limited domain would be something like f(x)=x, where the domain is greater than or equal to 0. S ince you can’t plot the square root of a negative on a standard plane, only positive numbers work as an input.

8th grade, so middle school. He has a twin brother who is in the same class. He seems to be a lot more thoughtful and systematic about his math, while his brother is convinced that he knows it and blasts through it to get back to his video games. And makes lots of mistakes along the way.

We phoned a friend (their uncle who teaches math) and he warned us about any denominator of zero or any square root of negatives.

Fo r whatever reason, I confused domain and range and thought that everyone else was nuts.

Sometimes I feel like I should go back and study math all over again. Yeesh.

Just Jeepin- if you hypothetically could purchase a comanche shell (front grill/some fender damage) for under 2 grand that is pristine underneath, would you consider that a good price? Found one localish, and have always dreamed of doing the 97+ front end, motor and interior swap, and this seems like the perfect candidate (no rust in the pics, bed and cab is straight, but light hit on the front )

Just Jeepin' > hedbutter

Afraid I’m not sufficiently clued in to have an opinion. Comanche prices seem pretty varied since there are so few on the market but they don’t seem to be benefiting from the classic truck/SUV bull market that’s driving up prices.

Sorry. I just don’t do enough MJ shopping and don’t know anything about restoration. Post it on Oppo and see what the cognoscenti say.
