Question

The main cable of a suspension bridge forms a parabola, described by the equation y = a(x â’ h)2 k. Y =height in feet of the cable above the roadway x =horizontal distance in feet from the left bridge support a =a constant (h, k) =vertex of the parbola What is the vertex of the parbola? ( , ).

Answer 1

The vertex of a parabola is the minimum or the maximum point of the parabola

The vertex of the given parabola is (h,k)

The equation of the suspension of the main cable is given as:

$y = a(x - h)^2 + k$

The above equation represents a parabola that passes through points (x,y) and (h,k)

Where point (h,k) represents the vertex of the parabola.

Hence, the vertex of the parabola is (h,k)
