Can someone check my work please?
Eva played her favorite video game for 14 hours last week. Today, Eva;s parents restricted her to 4 additional hours each week for the next 7 weeks. Creat the function, f(x), that midles Eva's total video game time, and explain what each number in the situation graphically, using complete sentences.

Best ResponseYou've already chosen the best response.0My function: f(x) = 14x + 7 x = 7 4 equals the yintercept, so you would start there then go up 14 and over 1. ** I don't think my explaination is right **

Best ResponseYou've already chosen the best response.0Restricting video game time? Such injustice haha Anyway, if she had 14 hours last week, and she gets an additional four hours every week, how many hours does she get this week? ^.^

Best ResponseYou've already chosen the best response.0Oops, I typed the function wrong. My function is... f(x) = 14x + 4 and x = 7

Best ResponseYou've already chosen the best response.0She would get 18 hours total for one week

Best ResponseYou've already chosen the best response.0Okay, great ^^ That's 14 + 4 when the number of weeks is 1. What about the second week?

anonymous

Best ResponseYou've already chosen the best response.0She would still get 18 hours. She will get 18 hours total for every week for 7 weeks. So she'll be playing video games for 126 hours over a period of 7 weeks.

Best ResponseYou've already chosen the best response.0No, she only gets four hours each week, right?

Best ResponseYou've already chosen the best response.0I thought that she got 14 hours a week plus an additional 4

Best ResponseYou've already chosen the best response.0Yeah, I thought so too, but that's not really restricting, is it?

Best ResponseYou've already chosen the best response.0Good point... so she'll only get 4 hours for 7 weeks?

Best ResponseYou've already chosen the best response.0After you get this done, you go deal with that git that wrote this problem... doesn't know how to phrase it correctly HAHA

Best ResponseYou've already chosen the best response.0Four hours per week, for the next seven weeks. So, week 1, she gets 18, which is 14 + 4 .... week 2, she gets 22, right? Because she's only allowed four more hours.

Best ResponseYou've already chosen the best response.0Okay... so the function I wrote is wrong?

anonymous

Best ResponseYou've already chosen the best response.0Looks like it. Incidentally, 22 is 18 + 8 or... 18 + 4(2) See the pattern here? ^^ week 1 > 18 + 4 week 2 > 18 + 4(2) week 3 > ????

Best ResponseYou've already chosen the best response.0Ooops... sorry, I was a too fast there. Shouldn't be 18, should be 14. My bad :D week 1 > 14 + 4 week 2 > 14 + 4(2) week 3 > 14 + 4(3) and so on, until week 7, yes? :D

Best ResponseYou've already chosen the best response.0So would the function be f(x) = 7x + 4 where x = 14 then?

anonymous

Best ResponseYou've already chosen the best response.0No... x is called a variable for a reason... that's because it's the part of the equation that actually changes :D You should keep everything else. So in 14 + 4(1) 14 + 4(2) 14 + 4(3) ... There's only one bit that changes... right?

Best ResponseYou've already chosen the best response.0I'm so confused on what the function would be then because my x variable can't keep changing, that's not how it works. It needs to be a number that continously makes the value increase by a certain number every single time otherwise it's not a function.

Best ResponseYou've already chosen the best response.0*continuously makes the value increase by a certain number...bla bla bla* to increase is to change, don't you see that? ^.^

Best ResponseYou've already chosen the best response.0You need to keep an open mind here :D 14 + 4(1) 14 + 4(2) 14 + 4(3) ...obviously, the only thing that changes here is that thing you multiply to 4. So your function should be y = 14 + 4x where x is the number of weeks

anonymous

Best ResponseYou've already chosen the best response.0So f(x) = 4x + 14 where x = 7

anonymous

Best ResponseYou've already chosen the best response.0Where x = the number of weeks that has passed _ For instance, after the first week, then x = 1 so the number of hours she will have played would be 14 + 4(1) or 18 which is exactly what you got earlier, right?

Best ResponseYou've already chosen the best response.0So the 7 that they put in the problem has nothing to do with function and the graph ._.

anonymous

Best ResponseYou've already chosen the best response.0It does. Just not something obvious. Technically, it means that the domain of the function is the set {0,1,2,3,4,5,6,7} In English, it means this function only applies for up to x = 7 Which is true. The restriction imposed on the poor bloke was "only" for seven weeks. So it's only right that we DON'T know how many hours she'll have played after eight weeks... the restriction may have been lifted or worsened by that point haha

Best ResponseYou've already chosen the best response.0Okay... so how am I supposed to graphically explain the function? f(x) = 4x + 14 so you start the y intercept on 14 and go up 4 and over 1 until you do it seven times?

anonymous

Best ResponseYou've already chosen the best response.0Yeah... only draw it until x = 7.

anonymous

Best ResponseYou've already chosen the best response.0I don't have to actually draw the graph, thankfully. Just explain how it would be graphed.

Best ResponseYou've already chosen the best response.0Yes, I very much do mind. But you're going to make me do it anyway, so let's hit it HAHA
