What is the focus of the parabola given by the equation y = x2 − 2x − 3?
y = x2 − 2x − 3
y = x2 − 2x − 3 -1 +1y = (x - 1)^2 - 4 h = 1 and k = - 4 and a = 1
Vertex (a, k) so it is (1,-4)
Now focus is
(1, -4 + 1/4) = (1,-3 3/4)
or
(1,-3.75)
Answer:
7+5x+9=−3x
7+5(-2)+9=−3(-2)
7+-10+9=6
-3+9=6
6=6
Step-by-step explanation:
7+5x+9=−3x
7+5(-2)+9=−3(-2)
7+-10+9=6
-3+9=6
6=6
Answer:
(Infinity sign,-3)- I don't know how to make an infinity sign.
If it doesn't have to be in an (x,y) format, then the range = -3
Step-by-step explanation:
The range is the set of numbers shown on the Y-axis (the domain would be the X-axis)
The Y axis only has one value, -3, and it extend on forever, hence the infinity sign.
Hope this helps.
