Answer: it’s b

Explanation:

edge

Answer 2

• domain: (-∞, ∞) \ (kπ+π/2 for integers k)
• range: (-∞, ∞)

Explanation:

The tangent function is undefined at odd multiples of π/2. It can take on any value.

The domain is all real numbers except odd multiples of π/2.

The range is all real numbers.
