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^214x3

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.
