Solve log₂(x − 1) = 3.

Worked method: Rewrite in exponential form: x − 1 = 2³ = 8, so x = 9. The domain condition x > 1 is satisfied.

Describe the end behaviour of f(x) = −2x³ + x.

Worked method: The leading term −2x³ controls the ends. As x → ∞, f(x) → −∞; as x → −∞, f(x) → ∞.

Solve 5^(x + 1) = 125.

Find the exact value of sin(5π/6).
