Answer:
Whats the question
Step-by-step explanation:
Answer:
The answer to your question is letter C.
Step-by-step explanation:
A. This option is wrong because that equation is of a horizontal parabola, an the graph shows a vertical parabola.
B. The same as letter A. This option is wrong because that equation is of a horizontal parabola, an the graph shows a vertical parabola.
C. This option is correct, is the equation of a vertical parabola and the negative indicates that it opens downward, as in the graph.
D. This option is incorrect because the equation is of a vertical parabola that opens upward.
Answer:
C) vertex: (-2, -4);
axis of symmetry: x = - 2
Step-by-step explanation:
One of the many ways to finding the vertex of a parabolic equation is to use the formula: for the x-coordinate of the vertex, and for the y-coordinate of the vertex.
However, since this equation is in vertex form, the simplest way to find the vertex would be by applying your knowledge of the vertex form of the parabola.
In this equation, we have the vertex form of a parabola: , where are the vertex coordinates.
In :
You may be wondering why h = -2 and not +2. This is because since the original vertex form is (x - h), this equation is basically subtracting a negative 2 to create a positive 2.
Now that we have the h and k values, we know the vertex:
The axis of symmetry is the vertical line that cuts right through the center point of the parabola, aka the vertex. Therefore, the axis of symmetry would be found by:
For this particular equation, h = -2, so the axis of symmetry would be:
