Find the equation for the axis of symmetry.
B.
Find the slope.
C.
Find the coordinates for the vertex.
D.
Plug in values for x around the vertex to get values of y
Is B correct?
you are correct.
A. Find the equation for the axis of symmetry: The axis of symmetry is a vertical line that divides the parabola into two symmetrical halves. The equation for the axis of symmetry is x = -b/2a, where a, b, and c are coefficients of the quadratic equation.
C. Find the coordinates for the vertex: The vertex is the highest or lowest point on the graph of a quadratic function. To find the coordinates of the vertex, you can use the formula x = -b/2a as mentioned earlier to find the x-coordinate, and then substitute that value back into the original equation to find the y-coordinate.
D. Plug in values for x around the vertex to get values of y: Once you have the vertex coordinates, you can choose values of x close to the vertex and substitute them into the quadratic equation to find the corresponding y-values. By doing this for a few points, you can plot them on the graph.
So, in summary, the correct answer is B - Finding the slope is not a step in graphing a quadratic function.
