Solution

To determine the vertical asymptote of the function f(x)=abx+cbx+ca f(x) = \frac{abx + c}{bx + ca} , follow these steps:

  1. Identify the denominator: The vertical asymptote occurs where the denominator is equal to zero because the function becomes undefined at these points. The denominator of the given function is bx+ca bx + ca .

  2. Set the denominator equal to zero: Solve for x x in the equation bx+ca=0 bx + ca = 0 .

  3. Solve for x x : bx+ca=0 bx + ca = 0 bx=ca bx = -ca x=cab x = -\frac{ca}{b}

Therefore, the vertical asymptote of the function f(x)=abx+cbx+ca f(x) = \frac{abx + c}{bx + ca} is at x=cab x = -\frac{ca}{b} .
