I'm assuming you meant to write y=-2x^2-3
There are 2 basic ways to find the vertex.
Since you're in algebra (I'm assuming) plug it into -b/2a. This will give you the x value for the turning point.
-b/2a
0/2(-2)
0
Now plug in 0 to the equation to get the y value.
y=-2(0)^2-3
y=-3
Ok so the point is (0,-3)
Best of luck!
Answer: Graph the parabola using the direction, vertex, focus, and axis of symmetry.
Direction: Opens Up
Vertex: (3, -1)
Focus: (3, - 3/4)
Axis of Symmetry: x = 3
Directrix: y = - 5/4
Step-by-step explanation:
graph{3x/(x^2-1) [-18.02, 18.02, -9.01, 9.02]}
Answer:
31.4 is the answer
Step-by-step explanation:
Answer:
you are trying to get up to 180 ( a straight line is 180 degrees).
So 26+32 =58 and go through your answer choices to see which one adds up to 180
and it that case your answer would be A 122+58=180
Step-by-step explanation:
Answer:
x = - 2
Step-by-step explanation:
Don't let the points disturb you. They are actually meant to confuse you.
