I was asked to deduce the values of a,b, and c for the parabola y= ax^2 + bx +c. There are 4 clues given:

1. the y-intercept is (0,6)

2. The curve goes through (4,5)

3. The curvev has a turning point at (2,3)

4. the line of symmetry is x=1

Questions: It is not possible for all clues to be true together (Why not?)

Which combinations of clues enable you to find a set of values for a,b and c?

Find the resulting parabola for each successful combination.

Tq..
