(03.04) For the function f(x) = -(x + 1)2 + 4, identify the vertex, domain, and range. (2 points) The vertex is (-1, 4), the domain is all real numbers, and the range is y ≥ 4. The vertex is (-1, 4), the domain is all real numbers, and the range is y ≤ 4. The vertex is (1, 4), the domain is all real numbers, and the range is y ≥ 4. The vertex is (1, 4), the domain is all real numbers, and the range is y ≤ 4.

Grace is standing 18 feet from a lighthouse and kelly is standing 10 feet from grace. the angle that grace looks up to see the top of the lighthouse is 45°. the angle that kelly looks up to see the top of the lighthouse is y°. find the height, h, of the lighthouse. find the angle, rounded to the nearest tenth of a degree, in which kelly looks up to the top of the lighthouse. to the nearest tenth of a degree, find the value of x° . in two or more sentences, explain your calculations
