For which function k does the output increase by 20% every time the input increases by 1?​

k(x) = 1.20^x

Step-by-step explanation:

Here, we want to get a function

The output in this case refers to k(x)

the input refers to the value x

So, for every 1 increase in x, we want k(x) to increase by 20%

20% is same as 20/100 = 0.2

So at an initial value of 1, each increase if 20% will be 0.2 + 1 = 1.2

So therefore, we have the function as;

k(x) = 1.20^x

none of the above.

for one of the equations to be used in the process, there has to be a term in the equation since squared is .

since there is only a term in the first equation, we cannot derive a from completing the square.
