Best ResponseYou've already chosen the best response.5suspect you have plotted it and got f'(x)=0 etc, etc so what do you think?

Best ResponseYou've already chosen the best response.0i think there is a loacl min bc it is the lowest

Best ResponseYou've already chosen the best response.0i would say theres no abs max bc we cant calculate how far its going up . so theres no abs max .

Best ResponseYou've already chosen the best response.0i would say local min

Best ResponseYou've already chosen the best response.5so it gets smaller somewhere else?

Best ResponseYou've already chosen the best response.5as in more negative

Best ResponseYou've already chosen the best response.5abs max = \(\infty\) look at the right and left ends of the curve, what does f(x) do?!

Best ResponseYou've already chosen the best response.0ohhh... so then itll be abs min bc its the lowest ?

marcelie

Best ResponseYou've already chosen the best response.0so itlll mostly be local min / max when it makes a curve ?

Best ResponseYou've already chosen the best response.5yes abs max = \(\infty\) abs min = whatever that bottom point is, because it never gets smaller

Best ResponseYou've already chosen the best response.0oh okay . lets say if i have 2 abs max ? so that means theres no abs max bc it exist 2. so it could only be one abs max ?

Best ResponseYou've already chosen the best response.0then abs min would be same as local min ?

Best ResponseYou've already chosen the best response.0wait... there would of been abs min but keeps goin on but nope theres no.

Best ResponseYou've already chosen the best response.5abs max and min are \(\infty\) and \(\infty\) local max and min are whatever they are.

Best ResponseYou've already chosen the best response.0abs max /min is the y vlaue ? locla min/max is the x and y values ?

IrishBoy123
 one year ago
Best ResponseYou've already chosen the best response.5in all cases you are concerned with the value of y because we are looking at 2D

IrishBoy123

Best ResponseYou've already chosen the best response.5so the global maximum is a question of how big and/or small y becomes as \(\infty \lt x \lt \infty\)

Best ResponseYou've already chosen the best response.0okay. is there an easier way to find abs max/min and local max/min ?

IrishBoy123
 one year ago
Best ResponseYou've already chosen the best response.5it depends on the curve but mostly calculus is king. eg find the max/min of \(y = 2x^{51} + 3x^{425}  2\)
