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)
The correct answer is B) its graph is symmetrical about the y-axis.
A quadratic graph cannot be "folded" across the x-axis.
The domain, or set of inputs, is all real numbers; there is no value of x for which there will be no y.
The range, or set of outputs, is not all real numbers; there are values of y that will not be used in the graph.
