An arch at a new amusement park is constructed with two vertical walls and parabolic arch top, where x represents the horizontal distance in feet and f(x) represents the height in feet.

the y-axis represents the vertical left edge of the arch. since the arch and it’s base are symmetrical, complete the equation for the line containing the vertical, right edge of the arch.

x=

The answer is x=60.

Since the arch and its base are symmetrical, so that other side of arch should be at (x, 20).  Refer to x-axis when y is equal to 20.  Thus, x=60.
