To determine the equation of the
exponential function that fits the given table, we can analyze the points
provided. The key points on the table are:
(0, 1)
(1, 0.6)
(2, 0.36)
(3, 0.216)
The general form of an exponential function
is , where a is the initial value and b is the base.
Notice the relationship between consecutive
y-values:
From (0, 1) to (1, 0.6), y goes from 1 to
0.6.
From (1, 0.6) to (2, 0.36), y goes from 0.6
to 0.36.
From (2, 0.36) to (3, 0.216), y goes from
0.36 to 0.216.
This consistent multiplication by 0.6
suggests that b=0.6.
Since (0, 1) is on the graph, substituting
x = 0 and y = 1 into the equation gives:
