The graph show a parabola with a vertex that has Roots are -2 and 4.
What is Parabola?
A parabola is a U-shaped curve this is drawn for a quadratic function,
f(x) = ax² + b x + c. The graph of the parabola is downward (or opens down), when the price of a is much less than 0, a < 0. The graph of the parabola is upward (or opens up) when the value of a is more than 0, a > 0.
Given that,
The vertex of (1,-9) and solutions of (-2,0) and (4,0).
y = k*(x+2)(x-4)
Vertex = (1,-9) is a point of the parabola
-9 = k*(1+2)(1-4)
Substitute the value of k = 1 in the equation,
The equation of the parabola is y = (x+2)(x-4).
