20.1 Nonlinear equations
Nonlinear equations
Nonlinear equations, as it says in its name, are any functions that are not linear, for example, quadratic, circle and exponential functions. In this lesson, we will learn how to graph nonlinear equations, and then determine whether they are a function or not. The easiest way to verify if an equation is a function, no matter if it is linear or nonlinear, is by using the vertical line test.

Notes:
NonLinear Equations: Basically any function that is not "linear equation", such as quadratic, circle, reciprocal, exponential, etc.

a)
$y = x^2 +2$

b)
$x = {1 \over 2} y^2$

c)
$y = {2 \over x}$

d)
$y = \sqrt {x  2}$

e)
$y = x^3  2$

f)
$x^2  y^2 = 9$
