c. Choose two functions from any set. Find the slope between consecutive points on the graphs.
For the first set slopes are 0.5 and 1, for the second set slopes are -0.5 and 0.5 for the third set slopes are
"A rational function is defined as the quotient of polynomials in which the denominator has a degree of at least 1"
If we are talking merely about x, then I get the concept. A rational function f(x) could be written as "
The issue that I'm having is that of talking about rational functions of n variables. For instance, what would be the meaning of 'f(x,y) is a rational function of
