If x is a number that is 7 more than y, how do you express x as a function of y?A. x = f(y) = 7 + x
B. x = f(y) = 7 + y
C. y = f(x) = 7x
D. y = f(x) = y – 7
E. y = f(x) = 7 + y

Answers

I believe the correct answer from the choices listed above is option B. The variable y is the independent variable here and x is the dependent variable so the function can be represented as f(y). The function should be written as:

x = f(y) = 7 + y
