Sketch the graph of the function y = –x2 – 20x – 3.
What are the domain and range of the function?
What are the x-intercepts? Approximate to two decimal places.
a. domain = [–30, ∞); range = (–∞, ∞);
x-intercepts: none
b. domain = (–∞, ∞); range = (–∞, 97];
x-intercepts: points (–0.16, 0) and (–19.85, 0)
c. domain = [–30, ∞); range = (–∞, ∞);
x-intercept: point (–0.16, 0)
d. domain = (–∞, ∞); range = (–∞, 97];
x-intercept: point (–0.16, 0)

i've got been Wiccan for 23 years and not heard of anybody naming a wand. So truthfully, on account that that's your guy or woman ingredient that feels good to you, call it what feels good to you. Insulting wand-naming isn't insulting Wicca-- because of the fact wand-naming isn't component to Wicca. lots of Wicca isn't Witchcraft-- it would not could incorporate Witchcraft in any respect. you would be able to could shop getting to grasp on that, because of the fact your assertion is merely incorrect.
