Answer :
Statement The value of a is positive, so the vertex is a minimum about quadratic function is true.
A quadratic function is one of the shape f(x) = ax2 + bx + c, where a, b, and c are numbers with a not same to zero. The graph of a quadratic feature is a curve called a parabola. Parabolas may additionally open upward or downward and vary, however they all have the identical simple "U" shape. any equation containing one term in which the unknown is squared and no term wherein it's miles raised to a higher power solve for x in the quadratic equation.
The graph of a quadratic feature is known as a parabola and has a curved shape. one of the primary points of a parabola is its vertex. In algebra, quadratic functions are any shape of the equation, wherein a isn't always equal to zero, which may be used to clear up complex math equations that try to compare missing factors in the equation through plotting them on a u-shaped figure referred to as a parabola.
