In the xy-plane, the graph of the function g is a parabola. The graph intersects the x-axis at (−4, 0) and (p, 0). If the vertex of g occurs at (−1, −18), what is the value of p ?
Vertex is (-1,-18), so the axis of symmetry is x = -1. (-4,0) is 3 units to the left of the axis of symmetry, so (p,0) is 3 units to the right of the axis. p = -1+3 =2
