Two exponential functions are shown in the table. A 3-column table has 5 rows. The first column is labeled x with entries 2, 1,
DanielleElmas [232]

Answer:

B. The functions f(x) and g(x) are reflections over the y-axis.

Step-by-step explanation:

From the information given the table appears as;

x            f(x)=2^x              g(x)=0.5^x

2               4                            0.25

1                 2                           0.5

0                1                             1

-1                0.5                         2

-2               0.25                       4

Plotting the two graphs to view the trends;

In the graph of f(x)=2^x against x you notice a curve with increasing positive slope.

In the graph of g(x)=0.5^x against x you notice a curve with a negative slope that is increasing.

In combining both graphs you notice that f(x) and g(x) are reflections over the y-axis.

Correct answer is ;The functions f(x) and g(x) are reflections over the y-axis.
