Question

If x is a number that is 7 more than y, how do you express x as a function of y?

Answer 1

f(x)=x+7?

Answer 2

x = f(y) = 7 + x
x = f(y) = 7 + y
y = f(x) = 7x
y = f(x) = y – 7
y = f(x) = 7 + y

Answer 3

so, whatever "y" is, "x" is 7 more than that

thus x = y + 7

Answer 4

y+7 or 7+y
the commutative property works the same anyhow

Answer 5

so it's either 2 or 5

Answer 6

x=7+y so x=f(y)=7+y
