Q:

please help asapWhich table shows the first four terms of the sequence described by :f(x)= 4(2)^xx f(x)1 8 2 163 324 64x f(x)1 82 643 5124 4069x f(x)1 42 83 164 32x f(x)1 42 63 84 10

Accepted Solution

A:
We have the following function:
 f (x) = 4 (2) ^ x
 Evaluating we have:
 For x = 1
 f (1) = 4 (2) ^ 1 = 4 * 2 = 8
 For x = 2
 f (2) = 4 (2) ^ 2 = 4 * 4 = 16
 For x = 3
 f (3) = 4 (2) ^ 3 = 4 * 8 = 32
 For x = 4
 f (4) = 4 (2) ^ 4 = 4 * 2 = 64


 Answer:
 The correct table is:
 x    f(x)
 1    8
 2    16
 3    32
 4    64
