A.There is a vertical asymptote at 0 and a hole at 3.
B.There are vertical asymptotes at -5/2 & 0 and a hole at 3.
C.There is a vertical asymptote at 3 and a hole at 0.
D.There are vertical asymptotes at 0 & 3

Answer:

We factor the function

f(x)= [ (2x + 5)(x-3) ]/[ 4x(x-3) ], x ≠ 3

f(x)= [ (2x + 5) ]/[ 4x ], x ≠ 3

A full cancellation of a denominator factor means that there will be a hole. The answer is that there is a vertical asymptote at 0 and a hole at 3.
