y = 0.7x2 - 5x + 3.4.
What is the minimum value of the function to three decimal places?
In what direction does the vertex of the function move when the coefficient 5 in the function is changed to a 6?
(changed to y = 0.7x2 - 6x + 3.4.)
+36916 minimum occurs at vertex for this bowl shaped parabola
at a value of x = - b/2a = - -5/(2* .7) Use this value of 'x' in the equation to calculate the minumim value of the function
the vertex will change to - b/2a = - -6 / (2 * .7) for 'x' and the 'y' value will be shifted down ( it will be shifted R and downward)
