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

Please show all of your work
f(x)=-7x^2-14x-3

1 answer

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.
