Instruction to make a quadratic function graph

1.   Choose  one of the quadratic function ( “ax²+bx+c “ is the general form of quadratics)

2.   Determine the confession of the x square (a) if the confession is positive the graph will be right side up and if the x square (a) is negative the graph will be right upper side down. It will remember you to guessing or image you graph that you will make.

3.   Determine the maximum or minimum value or vertex of the graph, x value can you find using this formula  -b/2a and  after that to find y value you can substitute the value of x maximum value first into the  function or you can use this formula -( b² -4ac)/4a and you can find the point (x , y)

4.   Determine the x - value point by input y = 0 to the quadratic function 0 = ax²+bx+c  and find the point ( x , y)

5.   Determine  the y - value point by input x = 0 to the quadratic function and find the point (x, y)

6.   Input  all of the point to the Cartesian diagram and plot the point by make a  line that connection between point  to become a parabola
