so how do u find x intercepts?
x intercepts occur where y = 0
so put f(x) = 0 into ur equation and solve for x first

its easier if u factorise the equation first tho
I'm not 100% sure on how to factorise it completely
all good: -x^2 + 48x -432 so what 2 numbers multiply to give 432... but adds to give 48? factors of 432 = 1,432, 2,216, 3,144, 4,108 6,72 8,54 9,48 12,36 16,27 18,24 so which 2 add to give 48 answer = 12 and 36
-x^2 + 48x -432 f(x) = ( -x +36 )( x - 12)
FOIL that: ( -x +36 )( x - 12) ( -x^2 +36x + 12x -432)
so, can you solve x intercepts?: f(x) = −x2 + 48x − 432 x intercepts are when f(x) = 0 0 = −x2 + 48x − 432 0 = ( -x +36 )( x - 12) therefore x = ??? or x = ???
I think I'm overthinking it xD
I got some crazy numbers
ok... well what about this: have u ever heard of the Quadratic Formula?
Yes, but I haven't learned anything about it
u can use this on a calculator or write out shorthand and solve urself using the values from ur equation in ur case: ur equation is: y = ax^2 + bx + c so a = -1 b = 48 c = -432 plug in and solve
12
Right?
or, easier: 0 = ( -x +36 )( x - 12) therefore either 0 = -x +36 or 0 = x - 12 ... yep, so one value is x = 12 so the other x value must be
36
perfect! so... the hard part... what does that mean?
|dw:1438576993181:dw|
I find the vertex which is the maximum profit
|dw:1438577109879:dw|
yep, vertex = max profit... what do the x intercept indicate tho?
They're the number of games sold
yeahh... so when they hit the x axis... they're not making any money... so like if they sold 11 or few units... they'd be losing money same as if they sold 33 or more copies... they'd be losing money
* sorry 37 or more copies
Okay I understand that
cools so what's the vertex? where do u start?
Do I substitute the x-intercepts into the equation?
nah, thats over... so we want the highest point on the curve, right have u done differentials yet? ie gradients
No
damn... i have no idea how to help u then, sorry :(
its the only way i know how to solve
Oh I think I know!
cool, shoot
There's this formula
Is the x-coordinate 24?
yep
so what was the formula?
\[x=\frac{ -b }{ 2a }\]
never seen it before, but hey, if it works, awesome!
Mhm. I think it's wrong, but is the y-coordinate 1,296?
no, should be 144 plug x = 24 into ur equation, u should get that
Yea I did something wrong there
But I see now
Thank you so much for your help!!!
np hey, u rock at these and good lucks
