Definition 1: Lipschitz Condition
A function f (t, y) is said to satisfy a Lipschitz condition in the variable y on a set D R2 if a constant L > 0 exists with |f (t, y1 ) - f (t, y2 )| L|y1 - y2 | whenever (t, y1 ), (t, y2 ) D. The

Y = -x3
Y = x3+4x2

It never has a vertical asymptote; this is shown by the limitless domain.
It always has a horizontal asymptote. This is shown by the limited range.
Exponential functions are never linear, they never have an unlimited range an

The Composition of Functions
Youve seen in previous activities that you can combine functions using arithmetic
operations. You can also create new functions from old ones by first applying one
function and then applying another.
Given two functions f and
Use the Polynomial Factors app to investigate the characteristics of polynomials and

1. Are the equations in the Polynomial Factors
My two equations were the standard equation of y=0.25x2-3x+10.5 and the transformation
equation of y=0.25(x-6)2+1.5. To convert from the standard, you would do this:

1. y = log2(x+1)
2. A logarithmic function always has a vertical asymptote. The domain tells us this because
it never reaches one point, but always gets closer
3. They never have horizontal asymptotes. The range confirms this because it is evergrowing.
