Answer:
(f o g) (x) = 36x² + 3
(g o f) (x) = 6x² + 18
Step-by-step explanation:
f(x) is x² + 3
g(x) is 6x
(f o g) (x) means for all xs in f replace it with g(x) or 6x
(f o g) (x) = (6x)² + 3 - see 6x is in place of x and 6x is g(x)
(f o g) (x) = 36x² + 3
(g o f) (x) = 6(x² + 3)
(g o f) (x) = 6x² + 18
15x - 10 where x is equal to the number of weeks would respresent the situation above. This is because he gains 15 cards every week and gave ten cards to James once.
If it has only been one week, the expression will be 15 - 10 because 15 × 1 = 15.
I hope this helps!
