Q. Which of the following equations represent functions where x is the input and y is the output? Select all that apply.Multi-select Choices:(A) y=1−x(B) y=x(C) x−y=1(D) x=1(E) y=−x−1
Analyze Equation (A): Analyze equation (A) y=1−x.- This equation can be rewritten for any x to find a corresponding y.- It's a function because for each x, there is exactly one y.
Analyze Equation (B): Analyze equation (B) y=x.- Direct relationship where each x corresponds to one y.- Clearly a function.
Analyze Equation (C): Analyze equation (C) x−y=1.- Rearrange to y=x−1.- Each x value gives one y value, so it's a function.
Analyze Equation (D): Analyze equation (D) x=1.- This equation does not define y as a function of x; it's just a vertical line.- Not a function because it doesn't pass the vertical line test.
Analyze Equation (E): Analyze equation (E) y=−x−1.- Similar to (A) and (B), each x corresponds to one y.- It's a function.
