x = 1 , x = 7
Explanation:
The denominator of the rational function cannot equal zero as this would lead to division by zero which is undefined. Setting the denominator equal to zero and solving for x will give the values that x cannot be and if the numerator is non-zero for these values of x then they must be vertical asymptotes.
solve: (x-1)(x-7) = 0 → x = 1 , x = 7
#rArrx=1,x=7" are the asymptotes"#
graph{1/((x-1)(x-7)) [-10, 10, -5, 5]}
