In this worksheet you will explore graphs of quadratic functions expressed in general [math]ax^2+bx+c[/math].
Q1:What change do you observe ?
Q2 When a is zero , the curve is a line. Why?
Q3 Is the curve passing through a fixed point? If yes, then what are the coordinates of this point?
Q4: As value of 'a' becomes larger (when a is positive), what is the effect on the shape of the curve?
Q5:As value of 'a' becomes larger (when a is negative), what is the effect on the shape of the curve.
Q6: How is the shape of the curve changing as the value of 'c' changes?
Q7: How is the shape of the curve changing as the value of 'b' changes?
Q8: What effect does changing values of 'b' has on the curve?
