Place the following in standard quadratic form. (which is (x-h)+k ). The find the vertex, axis, domain, range, and zeroes.

(can be all done with a calculator, no work needed.)

1. f(x) = x^2-8x+16

2. f(x)=16-x^2

3. f(x)=x^2+4x+5

4. f(x)= -x^2+2x+5

5. f(x)= 4x^2-4x+21

6. f(x)= 2x^2-x+1

ANYONE?
