The inside of a flashlight surrounding the bulb is shaped like a parabola in which the base of the bulb represents the vertex and the top of the bulb represents the focus. Which of the following standard equations represents the parabola in which the base of the bulb is at (1, 5) and top of the bulb is at (1, 1)? O (x + 1)= 20(y + 5) O (x + 1) = 16() + 5) O(x-1/=-20(y- 5) O (x-1)=-16(y- 5) A parabola is modeled with the equation x' - fix + 4y - 19 = 0. Which is the domain and range of the parabola
