idk how to,.. can u pls show me?

for yintercept, put x=0

iheartfoodBest ResponseYou've already chosen the best response.1
what do i plug that into?
 one year ago

hartnnBest ResponseYou've already chosen the best response.1
so yintercept is ab^(1/3) now since a and b are positive, yintercept is also positive.

iheartfoodBest ResponseYou've already chosen the best response.1
okay, so what does that mean??

iheartfoodBest ResponseYou've already chosen the best response.1
okay so how do i figure out between B and D?
 one year ago

hartnnBest ResponseYou've already chosen the best response.1
put y=0 in that equation

iheartfoodBest ResponseYou've already chosen the best response.1
which one? the one we just found?
 one year ago

iheartfoodBest ResponseYou've already chosen the best response.1
so i get this? 0=ab^(1/3) ??
 one year ago

hartnnBest ResponseYou've already chosen the best response.1
the original one 0=a(x+b)^(1/3) so x= ?
 one year ago

iheartfoodBest ResponseYou've already chosen the best response.1
so i get 0=(ax+ab)^1/3 ??? and idk how to find x= tho :(
 one year ago

hartnnBest ResponseYou've already chosen the best response.1
0=a(x+b)^(1/3) (x+b) = 0 (because a is positive and not 0, x+b must be 0) so x=b means x  intercept is negative

which graph among, B and d has xintercept negative ?
 one year ago

iheartfoodBest ResponseYou've already chosen the best response.1
okay, so hmmm is it B then?? the one i attached??

DID U UNDERSTAND HOW ITS DONE ?
 one year ago

iheartfoodBest ResponseYou've already chosen the best response.1
yeah :) find the intercepts and substitute and see whether it positive or negative... and u first find the first one and rule it out, then u narrow the answers down based on that intercept... then you find the next intercept and see if its pos or neg. and based on that u find ur graph. is that right? did i understand it correctly? :)
