Best ResponseYou've already chosen the best response.2there's a shortcut to knowing...just look at the exponents of *every* x. What are the exponents of every x in this case?

Best ResponseYou've already chosen the best response.04 & 1. would i add them? and its odd?

Best ResponseYou've already chosen the best response.2nope. remember: any constant is rewritten as cx^0 for example, 1 can be rewritten as 1x^0 2 can be rewritten as 2x^0 so 5 is 5x^0

Best ResponseYou've already chosen the best response.2so the exponents of x are actually 4, 1 and 0 got it?

Best ResponseYou've already chosen the best response.0yeah i get it. so its even?

Best ResponseYou've already chosen the best response.2now, look at 4, 1, 0 <are these numbers even, odd or neither?

logynklode

Best ResponseYou've already chosen the best response.0neither. because 4 even 1s odd

lgbasallote

Best ResponseYou've already chosen the best response.2so this polynomial is neither

Best ResponseYou've already chosen the best response.0thanks, can you help me with a few more?

Best ResponseYou've already chosen the best response.0before that, can you give me an example of an odd function? would that be like f(x) = 5x^6  4x^4  7x^2 ?

Best ResponseYou've already chosen the best response.2the exponents in this case are 6, 4 and 2..are those numbers odd?

Best ResponseYou've already chosen the best response.0true i meant even lol so that an even function

Best ResponseYou've already chosen the best response.0f(x) = 5x^5  4x^3  7 woul that be odd?

Best ResponseYou've already chosen the best response.1it would be except for the 7, which ruins it the degree of a constant is 0, and 0 is an even number

Best ResponseYou've already chosen the best response.2remember, i said constants have x^0 so 7 is actually 7x^0 0 is not odd

Best ResponseYou've already chosen the best response.0so f(x) = 5x^5  4x^3  7x ?

logynklode

Best ResponseYou've already chosen the best response.0or f(x) = 5x^7  4x^5  7x^3

lgbasallote

Best ResponseYou've already chosen the best response.2yes one has exponents 7, 5, 3 <all are odd the other is 5,3 ,1 <all are odd

Best ResponseYou've already chosen the best response.0okay. so the next question. Use the graph of f to estimate the local maximum and local minimum

lgbasallote

Best ResponseYou've already chosen the best response.2don't you just look at the "turning points" of that graph?

Best ResponseYou've already chosen the best response.0i thought so, but last tiem i got it wrong so i want to double check.

Best ResponseYou've already chosen the best response.0Local maximum: approx. (1,1.17); local minimum: approx. (2,3.33) ?

Best ResponseYou've already chosen the best response.2hmm...i'm not a master of graphs so i'm afraid i'll have to ask help from @helder_edwin

Best ResponseYou've already chosen the best response.0alright. theres one more. its graphs too tough. but i have choices, maybe that will help?

Best ResponseYou've already chosen the best response.2i think answers from @helder_edwin will be more precise

Best ResponseYou've already chosen the best response.0u r right. u got a local maximum at x=1 and a local minimun at x=2.

Best ResponseYou've already chosen the best response.0alright. i have one more. can you let me know if im correct?

Best ResponseYou've already chosen the best response.0i got Increasing x > 0; Decreasing x < 0

Best ResponseYou've already chosen the best response.0no. it is increasing over the entire real line
