Best ResponseYou've already chosen the best response.0So is it 2 and where line y= x+16 intercepts the x axis?

Best ResponseYou've already chosen the best response.1adnanchowdhury, bad drawing, it should only touch the xaxis

Best ResponseYou've already chosen the best response.1and yes, it is 2 and 16

Best ResponseYou've already chosen the best response.0Are you sure? because when x=0, y=16?

Best ResponseYou've already chosen the best response.1does not make a difference, you want y = 0

Best ResponseYou've already chosen the best response.1and y = 0. when x = 16

Best ResponseYou've already chosen the best response.1sorry, just read the question again, the roots are the solutions to the question, which means the intercepts between the 2 graphs: dw:1334914789804:dw

Best ResponseYou've already chosen the best response.1clearly one of the roots is at x = 0 and the only other root is where the line extends to meet the curve

Best ResponseYou've already chosen the best response.0okay, so there are 3 roots?

Best ResponseYou've already chosen the best response.1(x2)^4 = x+16 so x^4 8x^3+24x^232x+16 = x16

Best ResponseYou've already chosen the best response.116 cancels, and you can factor out x, so one solution is at x = 0

Best ResponseYou've already chosen the best response.1now, x^3 8x^2+24x32 = 0

Best ResponseYou've already chosen the best response.1this is a third order polynomial with one xintercept, so the solution to this equation, and x = 0, are the only 2 roots
