Question

y= -2x²(x+3) would this function stretch or compress ?

Answer 1

@dpaInc can you please help me out ?

Answer 2

As compared to...? something like: \[x^3 + x^2 \] ?

Answer 3

no using this a (k(x-d)) +c

Answer 4

@Calcmathlete can you help ?

Answer 5

Sorry...not sure :/

Answer 6

thanks anyways :)

Answer 7

I would think they mean to say what does it do to a function with no coefficients. I can't be sure. :/ Just think about what happens to y as the coefficients get extremely large. Then what happens when they are extremely small or nonexistant?

Answer 8

im just not sure if you consider the negative sign before the coefficient or not?

Answer 9

The negative would simply invert it. It would not have an effect on how rapidly the function grows.

Answer 10

so it would compress ? gahhh this is mind boggling

Answer 11

Stretching would mean that the curve grows vertically very very fast. Compression would mean that the curve grows more slowly and makes it look more short and squatty.

Answer 12

yes but i dont understand what this particular function would be doing

Answer 13

Well, if you distribute the -2x^2 you can see that it is a cubic, no?

Answer 14

ohh true true !

Answer 15

So if you imagine that the coefficients were lets say.... 10000, this function would grow extremely fast. If the coefficients were perhaps 0.001, the function would grow extremely slowly.
