For the function f(x) = –2(x + 3)2 − 1, identify the vertex, domain, and range. The vertex is (3, –1), the domain is all real numbers, and the range is y ≥ –1. The vertex is (3, –1), the domain is all real numbers, and the range is y ≤ –1. The vertex is (–3, –1), the domain is all real numbers, and the range is y ≤ –1. The vertex is (–3, –1), the domain is all real numbers, and the range is y ≥ –1.

read carefully if (x-h) = (x+3), what is h?

  • ofmiceparade
3
Vocaloid
  • Vocaloid
nope, think carefully x - h = x + 3 subtract x from each side, what do you get?
ofmiceparade
  • ofmiceparade
-3?

You divide it by negative h?
Vocaloid
  • Vocaloid
right, so h = -3 and our vertex is (-3,-1)
Vocaloid
  • Vocaloid
now, to find the range, we can see that the graph is a downward parabola, so our range is y <= -1
