Question

Function f is an exponential function.

Answer 1

If the 316 is supposed to be 3/16 and the 34 is supposed to be 3/4, then your answer is 2. 

Answer 2

Answer:

The output value increased by factor 2.

Step-by-step explanation:

The general form of the exponential function is

$f(x)=ab^x$

Where, a is initial value and b is growth factor.

From the given table it is noticed that at x=0, the value of f(x) is 3. It means the initial value is 3.

$a=3$

The another value of f(x) is 12 at x=2.

$f(3)=ab^2$

$12=(3)b^2$

$4=b^2$

$b=2$

The required function is

$f(x)=3(2)^x$

Since the growth factor is 2, therefore the output value increased by factor 2.
