Which set of ordered pairs represents a function from A to B? ​ A = {3, 2, 4, 1} and B = {–4, –5, 3, 2, 4}

answer for #1 is c

answer for #2 is d

can i get brainliest

for future students the answer is b

hope i

  or  

sin y = 7/q

7 is the opposite side length, q is the hypotenuse

tan y = 7/r

7 is the opposite side length, r is the adjacent side length

using sohcahtoa ^^^^

cos y = adjacent/hypotenuse

cos y = r/q

the graph line crosses the x axis at both -6 and -2, so the answer would be the second one.
