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=0(B) y−2x=6(C) 2x−y=6(D) y=x3(E) y=x2
Identify Function Criteria: Step 1: Identify if each equation represents a function where x is the input and y is the output. A function must assign exactly one output for each input.
Check Equation (A): Step 2: Check equation (A) y=0. This equation means y is always 0, regardless of x. This is a valid function because every x has exactly one y (0).
Check Equation (B): Step 3: Check equation (B) y−2x=6. Rearrange to y=2x+6. This is a linear equation where for each x, there is exactly one y. This is a function.
Check Equation (C): Step 4: Check equation (C) 2x−y=6. Rearrange to y=2x−6. Similar to (B), this is a linear equation and a function.
Check Equation (D): Step 5: Check equation (D) y=x3. This is a cubic equation. For each x, there is exactly one y. This is a function.
Check Equation (E): Step ext{6}: Check equation (E) y=x2. This is a quadratic equation. For each x, there is exactly one y. This is a function.
