he following models show the rate at which new members joined Facebook and MySpace in the period from 2005 to 2008: Facebook: f(t)=12t2−20t+10 million members per year MySpace: 10.5t2+25t+18.5 million members per year Where t is the years since the start of 2005. Which of the two internet sites experienced a larger influx of new members from the start of 2007 through June 2008? How many more members joined that internet site rather than joined its competitor during that perio
Equations and Inequations
Equations and inequalities describe the relationship between two mathematical expressions.
Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.
The following models show the rate at which new members joined Facebook and MySpace in the period from 2005 to 2008:
Facebook: f(t)=12t2−20t+10 million members per year
