It would be c because I used a graphing calculator lols
T1 = 4
4 = a
T5 = 16
16 = 4 + 4d
4d = 12
d = 3
Tn = 4 + ( n - 1 ) 3
Tn = 4 + 3n - 3
Tn = 3n + 1
the answer is b

The number of members in a baseball club is shown with the function:
f ( x ) = 25 * 1.45^x
When: x = 0: f ( 0 ) = 25
When x = 1 f ( x ) = 25 * 1.45 ≈ 36
When x = 3, f ( x ) = 25 * 1.45³ ≈ 76
Answer:
Graph D best represents this function.
