Question 948563
f(2) = 4
f(4) = -2


for example:


suppose you have a function that takes the value of x and squares it.


the function would be f(x) = x^2


now if you evaluate that function for the value of x = 2, you will get:


f(2) = 2^2 which becomes f(2) = 4


now if you have a function that takes the the square value of x and then multiplies it by -1, then that function would be:


f(x) = -sqrt(x)


now if you evaluate that function for when x = 4, you would get:


f(4) = -sqrt(4) which becomes f(4) = -2
