    Answer:

    Step-by-step explanation:

    Write the problem as a mathematical expression.

    y
    =2x−4

    y=x^2−4

    Substitute  x^2

    4  for  y  into  y
    =
    2
    x

    4  then solve for  x
    .

    x^2-4 = 2x-4

    x=0,2

    Substitute  2  for  x  into  y = 2x-4, then solve for y. Do the same with 0.

    y = 2(2)-4

    y=4-4

    y=0

    y = 2(0)-4

    y = 0-4

    y=-4

    Solution set:

    (0, -4)

    (2, 0)

    I hope this helps.
