ROUND 1: PRELIMINARY/SELECTION

• (-∞, ∞) b. (0,1)

• (0,1)

• (-1,1)

• a. (- π ≤ x ≤ π)
  

Answer explanation

The domain of the function sin-1x is (-1,1), as the range of sin(x) is -1 to 1, and the inverse function sin-1x will have a domain of (-1,1).

15 minutes to answer as many questions as possible. Top 2 groups from each set of 6-group competition will be selected for Round 2 onwards according to leaderboard score calculated by the application.

• (2,1)

• (2, -1)

• (2,3)

• (2, -3)

Answer explanation

To find the vertex of the quadratic equation x^2 - 4x + 3 = 0, use the formula x = -b/2a. In this case, x = -(-4)/2(1) = 2. Substituting x=2 back into the equation gives y = 2^2 - 4(2) + 3 = -1. Therefore, the vertex is (2, -1).
