Final answer:
The asymptote for a tangent graph is found at x = ±π/2.
Step-by-step explanation:
The asymptote for a tangent graph can be found at d) At x = ±π/2.
When we look at the tangent function, we can observe that it has vertical asymptotes at x = ±π/2. This means that as x approaches ±π/2, the tangent function approaches positive or negative infinity.
For example, when x = π/2, the tangent function is undefined because it would involve dividing by zero. However, as x approaches π/2 from the left side, the values of the tangent function increase without bound, approaching positive infinity. Similarly, as x approaches π/2 from the right side, the values of the tangent function decrease without bound, approaching negative infinity.
