What is the horizontal asymptote of the rational function f(x)=3x/(2x-1) What is the vertical asymptote of the rational function f(x)=3x/(2x-1) Write the following sentence as an equation: Y varies directly as x X is directly proportional to y and is inversely proportional to the cube of z Find the x-and y- intercepts of the cubic function f(x)=(x+4)(2x-1)(x-1) Need step by step example of each problem please. Thank you
