Me write a expression~
write a rule so that for every input, the output is an even number!

Answer with explanation:

A Rule which expresses that for every input, the output is an even number can be written in many ways

f(x)=2 x , where x is any Integer.

f(n)=4n,  where n is any Integer.

f(s)=6s,  where s is any Integer.

f(k)=8k,  where k is any Integer.

There can be many more expressions.

In these expressions,if you replace,x ,n,s and ,k by any integer , the result will be an Even Number(Positive Even Number or Negative Even Number).

step-by-step explanation:

yes, gavin is right.

step-by-step explanation:

gavin is correct. 

this problem is about converting 9% per year to how many percent per quarter. the rate is still the same. it only differed in the time period. so, through dimensional analysis,

9% per year  × (1 year / 4 quarters) = 2.25% per quarter

if he was asked to convert 9% per year to how many percent per quarter  compounded quarterly, then you will not simply divide by four. this is because compounding is not linear.

hope this , have a good day. c;
