Chapter 2

Direct Variation Function y=kx^n with k not equaling 0 and n>0
Inverse Variation Function y=k/x^n with k not equaling 0 and n>0
Slope y2-y1/x2-x1
Combined Variation Direct and inverse variations occur together Ex: y=kx/z
Joint Variation One quantity varies directly as the product of two or more independent variables but not inversely as any variable. Ex: y=kxz
Vertical Asymptote Values of x get closer and closer to the vertical line, the values of the function get larger and larger or smaller and smaller without bound. Ex: y=k/x and y=k/x^2
Horizontal Asymptote Values of x get very large or very small the value of y gets closer and closer to the x axis
