College algebra hw. need , don’t understand it, can someone explain this to me step-by-step?
55, 57, and 58 only

1, 9 and 12

Step-by-step explanation:

55

(f ○ g )(2) = f(g(2) ← from table g(2) = 3, thus

f(g(2)) = f(3) = 1 ← from table f(3) = 1

57

(g ○ f )(3) = g(f(3)) = g(1) = 9

58

(g ○ f )(6) = g(f(6)) = g(9) = 12

59

(f ○ f)(4) = f(f(4)) = f(3) = 1

the image of (6, 9) under a dilation is (4, 6). the scale factor is
