Answer:
A. -2, x= -2
Step-by-step explanation:
Answer:
A. 2
Step-by-step explanation:
B and D are equivalent.
because of the domain and range
1/x has same Domin and range as that of in D
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)
The answer is d. The y-intercept is at 4, the parabola is at 0 and the axis of symmetry is x=-2.
