Ответ:
At Saturday's game, there were 18 less than half of the fans that there were on Friday night.
This can be expressed by the expression:
1/2x - 18
Hope this helps! :)
Ответ:
f(x) = 48
Step-by-step explanation:
From the graph extract the points represented by the dots, that is
(1, 48), (2, 12), (3, 3)
The sequence is 48, 12, 3,
The explicit formula for a geometric sequence is
f(x) = a
where a is the first term and r the common ratio
Here a = 48 and r = 12 ÷ 48 = , thus
f(x) = 48
