Eva played her favorite video game for 14 hours last week. Today Eva's parents restricted her to 4 hours each week for the next 7 weeks. Create the function, f(x), that models Eva's total video game time and explain what each number in the situation represents, using complete sentences.

Question

idku · Answer

The question is kind of invalid, it is not clear.

 total video game time within last 7 weeks, all 8 weeks or what?

terenzreignz · Answer

Well actually, we just have to give it a little brain-crunching...
$$\Large f(\color{red}x) = ...$$

terenzreignz · Answer

Let x represent the number of weeks that have just passed...

terenzreignz · Answer

After one week, how many hours would she have played in total?

idku · Answer

So it's 8 weeks, (bye)

anonymous · Answer

let x = number of weeks 
let 4 represent hours per week
let 14 represent hours played prior to punishment
f(x) = (4x) +14
examine at weeks:
0
1
2
3
4
5
6
7

anonymous · Answer

to solve for total hours played solve for f(7)

anonymous · Answer

terenzreignz · Answer

anonymous · Answer
