Lesson 5: Rational Functions, Equations and Inequalities

Which of the following relationships of physical quantities can be modeled by rational function?

A bus travels a distance of 250 meters. Express velocity v as a function of travel time t, in seconds.

Which of the following is NOT a rational function?

f(x) = x/x-1

F(x) = -3^x

Let n be the degree of the numerator and m be the degree of the denominator.
If n > m,

If the degrees of the numerator (n) is less than the degrees of the denominator (m), y = 0 is

Setting q(x) =0 is the primary step in determining,

The real numbered zeroes are also _____________ of the graph of the function

The values of x which make the function zero.

The function value when x=0.

Point/s where the graph of the rational function intersects the x- or y-axis.
