How do you graph f(x)=2/(x-3)+1f(x)=2x3+1 using holes, vertical and horizontal asymptotes, x and y intercepts?

Below

Explanation:

f(x)=1+2/(x-3)f(x)=1+2x3

For vertical asymptote, look at the denominator. It cannot equal to 00 as the graph will be undefined at that point. Hence, you let denominator equal to 00 to find at what point the graph cannot equal to 00.

x-3=0x3=0
x=-3x=3

For horizontal asymptote, imagine what happens to the graph when x ->oox. As x ->oox, 2/(x-3) ->02x30 so f(x)=1+0=1f(x)=1+0=1 ie y=1y=1

For intercepts,
When y=0y=0, x=1x=1
When x=0x=0, y=1/3y=13

Below is what the graph looks like
