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. cos 60° = ; x = 6 feet
Step-by-step explanation:
apex
Answer:
For inequalities, the dot would be circled in because the value is greater than or EQUAL TO or less than or EQUAL TO.
Step-by-step explanation:
For example, x > 2 would have an open circle and you are NOT including the 2 that is inputted.
For x 
6, it would have a closed circle and you ARE including the 6 that is inputted.
