Neveah has created the function f(x) = (2x+4)/3 to represent the growth of her hair, where x represent the number of months since her last hair cut. Neveah discovers that using the inverse function to solve for x = 6, she can predict when her hair will have grown 6 inches. Explain to Neveah how to accomplish this, using complete sentences.

$$x = 2y + 4 \over 3$$ I think this is right inverse im not sure its what I got :P

anonymous · Answer

Ok, so how would I explain how to get to that answer?

anonymous · Answer

You understand inverses right?

anonymous · Answer

Er, no.

anonymous · Answer

Um an inverse is like when you reverse the operations to cancel out. like this 5 + 0 = 5 To cancel it out you would -5 from 5 to make the answer 0.

Peter played his favorite video game for 10 hours last week.  Today Peter's parents restricted him to 5 hours a week for the next 8 weeks.  

Create a function, f(x), that models Peters total video game time and explain what each number in the situation represents, using complete sentences.
