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.)

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)
