Provide a short answer to each question. What is the domain of the function ƒ(x)=1/x^2? What is its range?

The domain of a function refers to the set of all possible input values (x-values) for which the function is defined. For the function ƒ(x) = 1/x², the domain excludes any values that make the denominator zero, which in this case is x = 0. Therefore, the domain is all real numbers except zero, expressed as (-∞, 0) ∪ (0, ∞).

The range of a function is the set of all possible output values (y-values) that the function can produce. For ƒ(x) = 1/x², as x approaches zero from either side, the function approaches infinity, and as x moves away from zero, the function approaches zero but never reaches it. Thus, the range is all positive real numbers, expressed as (0, ∞).

A vertical asymptote is a line that a graph approaches but never touches or crosses, indicating where a function's value becomes unbounded. In the case of ƒ(x) = 1/x², there is a vertical asymptote at x = 0, which signifies that as x approaches zero, the function's value increases without bound, reinforcing the understanding of the domain and range.
