Answer:
x = 10 and x = -10
Step-by-step explanation:
Given the function
This function is undefied when the denominator equals to 0. Find these values for x:
This means that vertical lines x = 10 and x = -10 are vertical asymptotes (the graph of the function f(x) cannot meet these lines because this function is undefined at x = 10 and x = -10)
