(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

f(x) : ax²+bx+c, a≠ 0

[have to find the a(x-h)²+k form first]

Find an expression in terms of a, b, c for: (without using graph or calculator)

(i) An equation of the axis of symmetry

(ii) The maximum or minimum value

(iii) The coordinated of the vertex

(iv) The domain and the range

(v) The y-intercept of the graph of the function

(vi) The zeroes of the function

Discuss how you can predict the number of zeroes for a given quadratic function of the form y= ax²+bx+c, a≠ 0. Support the validit of your prediction with some examples.

My attempt was

(ax² + bx + b/2 - b/2) + c

(ax² + bx + b/2) + c - b/2

and after this i'm stuck

(v) y intercept is (0,c)
