This question asks to find:

(i) The equation of the parabola
(ii) coordinates of where the graph cuts y-axis
(iii) coordinates and nature of the Turning point
(iv) State the equation of the axis of symmetry of the parabola

There's a sketch given as well.

For the graph shown, at what values of x do you have y = 0? (x intercepts). Those are the values of 'a' and 'b'.

What are your thoughts?

Please share your work with us ...even if you know it is wrong

If you are stuck at the beginning tell us and we'll start with the definitions.

Thanks for your reply
we've been given b and c but no A
So the values given are b and c??

Im a secondary school student by the way.
(Doing national 5 in Scotland)
Thanks

The "a" was a typo. The point was that you're supposed to use what you know about the relationship between factors and x-intercepts in order to complete the quadratic equation. ;)
