Question 15 The graph drawn below depicts (A) ๐ฆ=ใ๐ ๐๐ใ^(โ1) ๐ฅ (B) ๐ฆ=ใ๐๐๐ ใ^(โ1) ๐ฅ (C) ๐ฆ=ใ๐๐๐ ๐๐ใ^(โ1) ๐ฅ (D) ๐ฆ=ใ๐๐๐กใ^(โ1) ๐ฅ We can solve this using options From graph For x = โ1, y = ๐ For x = 0, y = ๐/2 For x = 1, y = 0 Checking all options for x = โ1, 0, 1 For x = โ1 Option (A) - y So, the correct answer is (B) Question 15 The graph drawn below depicts (A) y=sin^(โ1) x (B) ๐ฆ=ใ๐๐๐ ใ^(โ1) ๐ฅ (C) ๐ฆ=ใ๐๐๐ ๐๐ใ^(โ1) ๐ฅ (D) ๐ฆ=ใ๐๐๐กใ^(โ1) ๐ฅ We can solve this using options From graph For x = โ1, y = ๐ For x = 0, y = ๐/2 For x = 1, y = 0 If we do normal trigonometry, then this basically means, For ฮธ = ๐, then __ ฮธ = โ1 For ฮธ = ๐/2, then __ ฮธ = 0 For ฮธ = 0, then __ ฮธ = 1 Since cos 0 = 1 And, cos ๐/2 = 0 โด This is graph of ๐=ใ๐๐๐ใ^(โ๐) ๐ So, the correct answer is (B)
