Question

Consider the function represented by the equation y – x – 4 = 0. What is the equation written in function notation, with x as the independent variable?

f(x) = x + 4
f(x) = –y + 4
f(x) = –x – 4
f(x) = y – 4

Answer 1

so given y - x - 4 = 0

y = x + 4

so this mean that f(x) = x + 4 will be the right answer sure
