(Figure) represents the graph of the quadratic function written in general form asy=x2+4x+3.y=x2+4x+3.In this form,a=1,b=4,a=1,b=4,andc=3.c=3.Becausea>0,a>0,the parabola opens upward. The axis of symmetry isx=−42(1)=−2.x=−42(1)=−2.This also makes sense...
The graph of a quadratic function is a parabola whose axis of symmetry is parallel to the yy-axis. The coefficients a,b,a,b, and cc in the equation y=ax2+bx+cy=ax2+bx+c control various facets of what the parabola looks like when graphed. Key Terms vertex: The maximum or mi...

The parabolic graph of a quadratic function is symmetrical about axis of symmetry. f(x) has a minimum value at vertex if a>0 and at f(x) has a maximum value at vertex if a<0 and at In the next post about quadratics, I shall discuss discriminant, nature of roots, relationships betwe...
Axis of symmetryThe quadratic formula learned by generations of math students is difficult to remember, but it can be used to solve quadratic equations where y = 0. Solving the equation gives the two points where the parabola crosses the x-axis (the two values of x when y = 0):What ...
Quadratic equations are used to find the zeroes of the parabola and its axis of symmetry. There are many real-world applications of quadratic equations. They can be used in running time problems to evaluate the speed, distance or time while traveling by car, train or plane. Quadratic equations...
