A description is given of how the function f (x) changes the variable x. Write down the function rule for the following:
Function f (x) reduces the number x by 
.
A function reduces the number x by 
.
The dependent variable is twice the independent variable in a function.
The dependent variable is 
times less than twice the independent variable in a function.
The value f (x) is less than a quarter of the number x.
The dependent variable is 
greater than five times the independent value in a function.
The function f (x) is 
greater than the additive inverse of the number x.
The dependent variable is 
less than six times the additive inverse of the independent variable x.
A function decreases the multiplicative inverse of the number x by .
The dependent variable of a function increases the multiplicative inverse of the number x by .
The function f is the square of the independent variable.
A function increases the absolute value of the number x by .
The dependent variable of a function is the absolute value of the multiplicative inverse of the independent variable.
A function is one-fifth of the sum of the numbers x and .
The dependent variable is half the difference of the additive inverse of the number x and .
