@SierraMath1 Looks like a piecewise function to me. I'd say the equation is f(x)=...
{ 2x, x ≤ 0
{ x, x ≥ 0
{ -x+4, x ≥ 2

@STAB_MATH Aren't all of the 12 basic functions able to be possibilities, since x=1 is in all of their domains?

[Mariam Topchyan @mtopchyanmath]

@StabMathJordyn I believe it would look something like this, but do correct me if I'm wrong. (Original function is red, flipped is blue)

@STAB_MATH The graph most likely was not an actual function -- it probably didn't pass the vertical line test.

@McNamaraMath19 Pretty sure you can take a -3 out as a GCF

[Mariam Topchyan @mtopchyanmath]

All quadratic functions have a domain of all real numbers ( ℝ ).

[Mariam Topchyan @mtopchyanmath]

Kind of confused on limits. Sorry if this is a stupid question, but I was absent. Does DNE on the homework mean "Does not exist", or...?

[Mariam Topchyan @mtopchyanmath]

@STAB_MATH The domain is all real numbers. The range is ≥ 0 because no matter what you square, it'll be positive.

I was sick and absent last class. Can anyone tell me what we went over in class yesterday? Thanks!

[Mariam Topchyan @mtopchyanmath]

@tessmajorsmath I think you're just supposed to make up a machine like that of your own with a list of inputs/outputs and whatever else the questions ask

[Mariam Topchyan @mtopchyanmath]

@tessmajorsmath Not sure if I'm right, but I think it's like what we did in class, a theoretical object w/ an input and an output, like box(penny) = marker

[Mariam Topchyan @mtopchyanmath]

@cstrasburg_math Yup, believe so. That's what I got as well

[Mariam Topchyan @mtopchyanmath]

@STAB_MATH On right, x applies to all terms, so you can safely take out one x each. On left, you need to take out ALL x's, not just one. (Factoring)
