Answer 1

Answer:

Option B.

Step-by-step explanation:

Note: The function f(x) is not in correct format it must be $f(x)=3^x$.

It is given that two different plants that grow each month at different rates are represented by the functions f(x) and g(x).

Let as consider the two functions,

$f(x)=3^x$

$g(x)=5x+12$

Now, table of values is

Month(x)        $f(x)=3^x$           $g(x)=5x+12$

    1                      3                          17

    2                     9                         22

    3                     27                        27

    4                     81                        32

From the above table it is clear that in first and second month the height of the f(x) plant is less than of g(x).

In month 3, heights are equal.

In month 4, height of the f(x) plant exceed that of the g(x) plant.

Therefore, the correct option is B.
