Question

Help!!!
Explain what factored form a quadratic function helps you to graph and give and example.

Please help!

Answer 1

the binomial and vertex form

Answer 2

Ohhh okay (:

Answer 3

an example:

y = x^2 + 4x - 5
factor:
y = (x + 5)(x - 1)
- so the zeros (x-intercepts) are -5 and 1
vertex form

y = (x + 2)^2 - 9

- this gives you the coordinates of the minimum value , in this case its (-2,6)
