solve the following using row reduction
f(x) = (5x + 4) / x^3
A) The domain is all real numbers except 0
B) x-intercept is (-4/5, 0), no y-intercept
C) horizontal asymptote is x-axis or y = 0, vertical asymptote is y-axis or x = ...
This provides an example of working with critical numbers of a function and solving a system of equations.
