If f(x) = 1/(x? + 1), what is f(2)? What is f(y? )? 2?

Step-by-Step Solution:

Step-by-step solution Step 1 of 3 Consider a given function It is very simple tofind f (2), we only have to put =2 in the fu nction f: So, Step 2 of 3 2 2 Similar as in previous step It is very simple to find f(y ), we only have to put x =y in the function f: 2 2 3 f(y ) = 1/((y ) + 1) b Based on the rule (x ) = x ab we can write the following: f(y ) = 1/(y + 1)
