f(x)=2x/ (x−17)

(a) Find the zeros of f(x). If there are none, enter DNE in all capital letters.

wouldn't it be x =0 and x =17....it says it's wrong

thanks

(a) since 0/x=0, f(0) = 0

f(17) = 34/0
x=17 is excluded, because division by zero is undefined

x = 17 results in a zero in the denominator of the fraction

division by zero is undefined
