Can someone please explain to me what the horizontal asymptote is?
A function $f$ has a horizontal asymptote of $y = -4,$ a vertical asymptote of $x = 3,$ and an $x$-intercept at $(1,0).$ Part (a): Let $f$ be of the form Find an expression for $f(x).$ Part (b): Let $f$ be of the form Find an expression for $f(x).$
Please explain why f(x) would equal a and equal -4... I don’t understand!!!(please also explain about the vertical asymptote as well... THANK YOU!!!
