Given the following function, find:
(a) vertex
(b) axis of symmetry

(c) intercepts,

(d) domain
(e) range

(f) intervals where the function is increasing,
(g) intervals where the function is decreasing

f(x)=-7x^2-14x-3

• algebra -

you have a parabola opening downward
f(x) = -7(x+1)^2 + 4

That should help you answer the questions. If not, come on back and say where you get stuck.
