Best ResponseYou've already chosen the best response.1I've already completed 96% of the question. My final answer is y=149x+4481, but the textbook says it is y=1491x+3648

Best ResponseYou've already chosen the best response.1I got \(y=1491x+3648\) as well..probably you did something wrong

Best ResponseYou've already chosen the best response.1Er...what did you get as your yvalue?

Best ResponseYou've already chosen the best response.1\[yy_1 =m(xx_1)\] \[y+825=1491(x3) => y+825=1491x+4473 => y3648=1491x\] \[=> y =1491x+3648\]

Best ResponseYou've already chosen the best response.1How did you get your yvalue? I did this:\[y=((3)^{3}+2)(4(3)^{2}3)\]

Best ResponseYou've already chosen the best response.1The minus is inside the bracket.

Best ResponseYou've already chosen the best response.1\[y=((3)^3+2)(4(3)^23)\]

Best ResponseYou've already chosen the best response.1then the yvalule is \(825\)

Best ResponseYou've already chosen the best response.1No, I don't think the minus sign is inside the bracket... My equation is this actually, sorry. \[y=(−(3)^{3}+2)(4(3)^{2}−3)\] I'll try what you said though.

Best ResponseYou've already chosen the best response.1Hmm..is it \[P(x) = (x^3+2)(4x^23)\] ?

Best ResponseYou've already chosen the best response.1Ignore what I said. Thanks. I got it.
