Answer:
Step-by-step explanation:
x² - 6x + 7
To evaluate (f ￮ g)(x), substitute x = g(x) into f(x), that is
f(g(x))
= f(x - 3)
= (x - 3)² - 2 ← expand factor using FOIL
= x² - 6x + 9 - 2
= x² - 6x + 7
correct
1) 15/60 = 3/12 = 1/4
2) 8/36 = 4/23
f ( - 2 ) = 5 × 3^( - 2 )
f ( - 2 ) = 5 × 1/9
f ( - 2 ) = 5/9
