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:
a line
Step-by-step explanation:
In geometry, we can define a line as a straight one- dimensional figure without thickness but extends infinitely in both directions.
If we are to put it into more understandable words, we can describe a line as the shortest distance between any two points.
A line has a specific definition in geometry. Every other option listed do not have specific definition in geometry.
Y=70x
