Answer:
On a coordinate plane, a parabola opens up
It goes through (negative 3, 0), has a vertex at (negative 0.5, negative 6.25), and goes through (2, 0).
Step-by-step explanation:
f(x) = (x + 3)(x – 2)
We know that parabola opens up since the x^2 term is be positive
it has zeros at x=-3 and x=2
x+3 =0 and x-2 =0 from the zero product property
The vertex is halfway between the zeros
(-3+2)/2 = -1/2
x=-1/2
f(-1/2) = (-1/2+3) (-1/2-2) = 2.5 * -2.5 =-6.25
The vertex is (-1/2, -6.25)
f(x) = (x + 3)(x – 2)

What is the equation of a parabola?
Parabola Equation
The general equation of a parabola is: y = a(x-h)2 + k or x = a(y-k)2 +h, where (h,k) denotes the vertex. The standard equation of a regular parabola is y2 = 4ax. Some of the important terms below are helpful to understand the features and parts of a parabola.
What is a parabola in a graph?
A parabola is a U-shaped curve that is drawn for a quadratic function, f(x) = ax2 + bx + c. The graph of the parabola is downward (or opens down), when the value of a is 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.
