    y-intercept is equal the value of function for x = 0.

    Put x = 0 to the equation y + 4 = (x + 2) ²

    y + 4 = (0 + 2) ²

    y + 4 = 2²

    y + 4 = 4 |-4

    y = 0

    Answer: y-intercept = 0 → (0, 0)

    The normal quadratic equation would be y=ax^2+bx+c.

    The variable c is the y intercept, so let's get y to itself.

    y+4 = (x+2) ^2 (square this side.)

    y+4=x^2+4x+4 (subtract the 4 on the y side to isolate the y.)

    y=x^2+4x

    The y intercept is zero.
