The axis of symmetry is negative, so h must be negative. This means in the standard form of the equation the parentheses must be (+ h); eliminate (A) and (C). Finally, the vertex of the parabola is positive, so k must be positive; eliminate (D) and choose (B) ...
The parabola's axis of symmetry (x = h) is a vertical line passing through the vertex, so as demonstrated above, this is x = 1. 4. Calculate the X-intercepts You can solve it using the quadratic formula: x = -b ±√(b² – 4ac) / (2a). Substitute the values of a, b and...
A parabola is a curve where each point of the curve is equidistant from a point called the focus and a straight line called the directrix. All parabolas have a focus and a directrix and every point of the parabola is equidistant from these. The axis of symmetry is is the line that bisec...
