Answer: amplitude
Step-by-step explanation: The amplitude represents half the distance between the maximum of a sine or cosine graph.
X-coordinate: -.50
Y-coordinate: -.55
1 and 2 are vertical
3 and 4 are adjacent
You cannot factor it, so there is no simplification. The Constants "4" and "9" do not share a common factor, therefore, you cannot simplify it. However, if it was a number such as "8" replacing "9", then you can simplify by doing:
4(x^2 - 2) = 4x^2-9
4%of 500 = 20
500 plus or minus 20 gives range as (480,520)
