Coefficients of a general quadratic function
Review your knowledge on graph of quadratic functions.
How do the coefficients a, b, and c affect the graph in terms of
(i) shape (U (parabolic) or inverted U (inverted parabolic)
(ii) position of the line of symmetry ( vertical line through x value of turning point )
(iii) the y intercept, where the curve cuts the y axis.
