a) the vertex

b) the axis of symmetry

c) the intercepts

d) the domain

e) the range

f) the interval where the function is increasing

g) the interval where the function is decreasing

h) graph the function

y= -x^2-6x

- Please help! quadratic equation -
**Reiny**, Saturday, March 16, 2013 at 12:32pmI will complete the square for you

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

= -(x^2 + 6x + 9 - 9)

= -( (x+3)^2 - 9)

= -(x+3)^2 + 9

I you are studying this topic, then you MUST be able to answer the given questions from this result.
