This Choose all that correctly give the inverse function values.

f = {(1,0), (4, 5), (6, 9)} F1 = {(0, 1), (5, 4), (9,6)}

f = {(2, 3), (4,7), (9.12)} F1 = {(3, 2), (7,4) (12,9)

f = {(1,3), (4,5), (6,8)} f1 = {(-1,3), (-4,5).(-6,8)]

f= {(3,5), (4, 6), (1,9)} F1 = {(-5,3), (-6,4) (-9,7)}

f = {(5,7), (7,8), (9, 11) F1 = [(7,5), (8, 7), (11,9)}​

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°

the answer is c
