SOLUTION
In this question, we are meant to expand the expression:
It means that the two line segments, EF and GH, are A, parallel.
The symbol between the segments (ll) is of two parallel lines, so it's stating that the segments are parallel.
The graph of a quadratic function is a parabola. The axis of symmetry<span> of a parabola is a vertical line that divides the parabola into two congruent halves. The </span>axis of symmetry<span>always passes through the vertex of the parabola . The x -coordinate of the vertex is the equation of the </span>axis of symmetry<span> of the parabola.</span>
