so looking at this craft, first we see that the interval of decrease is from 0 to 2.7165 and the interval from think of increases from 0.717 to infinity. Then we see that in terms of the concocted E Um, this right here has a negative slope. So it's conclave down from zero to point for 36 for 346 And that's con Cape, up from 0.4346 All the way. Teoh infinity.
