Write each equation using function notation.

1. y − 2x = 5

2. y − 3x = 8x − 10

3. 2y + 6x = 10

4. −x2 = 7 − y

The answer to your question is  1.-   f(x) = 2x + 5    2.-   f(x) = 11x - 10

                                                     3.-   f(x) = -3x + 5   3.-  f(x) = x² + 7

Step-by-step explanation:

Equations

1.- y - 2x = 5

- Solve for y

   y = 2x + 5

- Use function notation

  f(x) = 2x + 5

2.- y - 3x = 8x - 10

-Solve for y

    y = 8x - 10 + 3x

- Simplify

    y = 11x - 10

-Convert to function notation

   f(x) = 11x - 10

3.- 2y + 6x = 10

-Solve for y

    2y = -6x + 10

      y = -6/2x + 10/2

-Simplify

     y = -3x + 5

-Convert to function notation

    f(x) = -3x + 5

4.- - x² = 7 - y

-Solve for y

     y = x² + 7

-Convert to function notation

    f(x) = x² + 7
