OpenStudy (henrietepurina):

any ideas @mathmath333 ?

OpenStudy (henrietepurina):

@jagr2713 :D Sorry to call you back but I need help :P

OpenStudy (mathmath333):

i think u have to make a table containing \(x\) and \(f(x)\) with values of \(x\) same as \(0.6,0.8,1,1.2,1.4\) use the formula given to find that \(f(x)=0.05x^2-7x+300\)

OpenStudy (henrietepurina):

ok then... so the answer for 0.6 is 295.8009

OpenStudy (mathmath333):

and then find if the if any values of \(f(x) \) is less than \(g(x)\)

OpenStudy (mathmath333):

u have to find all the values of \(f(x)\) for values 0.6,0.8,1,1.2,1.4

OpenStudy (mathmath333):

295 is correct for \(x=0.6\)

OpenStudy (henrietepurina):

ok...

OpenStudy (mathmath333):

if every values of \(f(x)\) is less than \(g(x)\) then company \(1.\) has minimum cost production

OpenStudy (henrietepurina):

so far. it looks like company 2 has the greater cost

OpenStudy (mathmath333):

then it would be company \(2.\)

OpenStudy (henrietepurina):

let me check the rest quickly

OpenStudy (henrietepurina):

yeah, the greater cost is for comp. 2 for all

OpenStudy (henrietepurina):

but I can't understand the question Based on the given information, the minimum production cost for company _____ is greater.

OpenStudy (henrietepurina):

is it asking for the one with less or bigger prices?

OpenStudy (mathmath333):

oh so it asks for less values of \(f(x)\) or \(g(x)\)

OpenStudy (mathmath333):

so it would be \(f(x)\) i think

OpenStudy (mathmath333):

that is company \(1.\)

OpenStudy (henrietepurina):

you sure?

OpenStudy (henrietepurina):

I think it's asking for company 2, because of the key word "greater"

OpenStudy (mathmath333):

have u found all values for \(f(x)\)

OpenStudy (henrietepurina):

yeah, and they're all less for comp. 1

OpenStudy (mathmath333):

then its company \(\huge 1.\)

OpenStudy (henrietepurina):

how come its asking who's minimum values, are greater

OpenStudy (mathmath333):

the question is asked in a way just to confuse the students
