The vertex is (-1,1)
Explanation
The vertex formula to find the x coordinate of the formula is -b/2a
So we plug in the values into the formula which is
-4/2(2)
Simplify it
-4/4
=-1
-1 is now the x cord of the vertex.
So now we will plug in the x into the quadratic equation which is 2x^2+4x+3
2(-1)^2 + 4(-1) + 3 = 2 -4 +3
Simplify it
5 - 4= 1
Y=1
So the Coordinates of the vertex is (-1,1)
Answer:
12.56
Step-by-step explanation:
If a circle has a diameter of 4, its circumference is 3.14*4=12.56.
I’m pretty sure it’s B because you can put in any number and it could still have a difference of 1
Answer:
B.
