If x is a number that is 7 more than y, how do you express x as a function of y?
A function shows the relationship between two variables where one of them is independent and the other being the dependent variable. For a function, every x should have a unique value of y.
Answer: If x is a number that is 7 more than y, then x as a function of y is expressed as f (y) = x = 7 + y.
Let's express x as a function of y.
Explanation:
Given: x = 7 + y
The statement x as a function of y means that the value of x varies with th value of y.
⇒ f ( y ) = x
⇒ f ( y ) = x = 7 + y
⇒ For every value of y the value of function changes.
Thus, f (y) = x = 7 + y is the solution.
