Questions & Step-by-Step Solutions
Which of the following functions has a vertical asymptote?
Step 1: Understand what a vertical asymptote is. A vertical asymptote occurs when a function approaches infinity as the input (x) approaches a certain value.
Step 2: Look at the function f(x) = 1/(x - 2). This function is a fraction where the denominator is (x - 2).
Step 3: Identify when the denominator equals zero. Set (x - 2) = 0 to find the value of x that makes the function undefined.
Step 4: Solve for x. Adding 2 to both sides gives x = 2.
Step 5: Conclude that at x = 2, the function f(x) is undefined, which means there is a vertical asymptote at this point.
