3. graph the function and identify the vertical asymptote. y=1/x-4-2 4. graph the function and identify the vertical asymptote. y = 1/x+2+4

I can't do much graphing on here but the first equation has a vertical asymptote at x = 4. You get this by taking the denominator (x - 4) and setting it equal to zero. The answer x = 4 will be the asymptote.

The second equation will have a vartical asymptote at x = - 2.

Again taking the denominator (x + 2) setting it to zero and solve. x = - 2 will be the solution ans the asymptote.
