Which graph represents a geometric sequence?
A
On a coordinate plane, 5 points are plotted. The points are (1, 1), (2, 3), (3, 5), (4, 7), (5, 9).
B
On a coordinate plane, 4 points are plotted. The points are (1, 1), (2, 2), (3, 4), (4, 8).
C
On a coordinate plane, 3 points are plotted. The points are (1, 2), (4, 4), (9, 6).
D
On a coordinate plane, 3 points are plotted. The points are (1, 1), (2, 4), (3, 9).
5
On a coordinate plane, 3 points are plotted. The points are (1, 80), (2, 20), (3, 5).
A
f(x) = 80
B
f(x) = 320C
f(x) = 80(4)x – 1D
f(x) = 320(4)x – 16
Pablo generates the function to determine the xth number in a sequence.
A
f(x + 1) = f(x)
B
f(x) = f(x + 1)C
f(x + 1) = f(x)
D
f(x) = f(x + 1)7

A bouncing toy reaches a height of 64 inches at its first peak, 48 inches at its second peak, and 36 inches at its third peak. Which explicit function represents the geometric sequence of the heights of the toy?
A
f(x) = 48
B
f(x) = 48C
f(x) = 64D
f(x) = 6410
Sebastian writes the recursive formula f(x+1) = 4f(x) to represent a geometric sequence whose second term is 12.
A
f(x) = 12(4)xB
f(x) = 3(4)x − 1C
f(x) = 4(12)xD
f(x) = 4(3)x − 1Did you find these answers helpful?
