A quadratic function is graphically represented by a parabola with a vertex located at the origin, below the x-axis, or above the x-axis. .
The points at which the graph crosses or touches the x-axis, give the real roots of the function(or zeros of the function) represented by the graph.
If the graph touches the x-axis and turns back, then it would be a double root at that point. Roots are also called x-intercepts or zeros.
The roots of the graph are Option B -4, -2, 1, and 3.
The standard form of a quadratic is y = ax^2 + bx + c, where a, b, and c are numbers and a cannot be 0. Examples of quadratic equations include all of these: y = x^2 + 3x + 1. y = x^2.
The quadratic equation in its standard form is ax2 + bx + c = 0, where a and b are the coefficients, x is the variable, and c is the constant term. The first condition for an equation to be a quadratic equation is the coefficient of x2 is a non-zero term(a ≠0)
