ill the line of symmetry pass through on the curve?
Which axis does the line of symmetry cut 

# data[].attributes.body
-The line of symmetry passes through the turning point of the curve.
-the line of symmetry passes through the x-axis

1.  The y-intercept is the same as c in the equation
2.  The x intercept is the point of the curve where it intercepts with the x axis.The y intercept is the point of the curve where it intercepts with the y axis
3. A curve can have a maximum 2 x-intercepts

There can be no x-intercept when the curved line does not hit the x-axis. There can be 2 x-intercepts when the curved line cuts the x-axis and curves down to cut it again. There can also be 1 x-intercept when the turning point is exactly on the x-axis

the shape of the curve when
i) a > 0 the graph opens upwards. The shape if the graohbis similar to a happy face or a u-shape. The graph has a lowest point, called the minimum point
ii ) When a < 0 the graph opens downwards. The shape if the graph us similar to a sad face or a n-shape. The graph has a highest point, called the maximum point.

If you can reflect (or flip) a figure over a line and the figure appears unchanged, then the figure has reflection symmetry or line symmetry. The line that you reflect over is called the line of symmetry. A line of symmetry divides a figure into two mirror-image halves.

When a is greater than 0, the turning point of the curve is the lowest point

1) An equation is made up of 3 variables "a+b+c" Take this equation for example :  4x ² + 4x - 2
In this equation,  4x ² is "a", 4x is "b", and -2 is "c" The value of "c" is the y-intercept. Therefore, the y-intercept is -2.

2) There are 2 "x-intercepts" and only 1 "y-intercept" from the curve in a graph. To find the 2 "x-intercepts", look at the 2 points in where the curve touches/cuts across the x axis in the graph. To find the "y-intercept", look at the point in which the curve touches/cuts across the y axis. There should only be 1 point where the curve touches/cuts across the y axis. That is how you find the "x-intercepts" and "y-intercept" in the graph.

3) In a curve, there are 2 "x-intercepts".

The axis of symmetry always passes through the vertex of the parabola . The parabola is a curve. The x -coordinate of the vertex is the equation of the axis of symmetry of the parabola. For a quadratic function in standard form, y=ax2+bx+c , the axis of symmetry is a vertical line x=−b2a .

The graph of a quadratic equation in the form x = a y 2 + b y + c has as its axis of symmetry the line y = − b 2 a . So, the equation of the axis of symmetry of the given parabola is y = − 4 2 ( 1 ) or . Substitute in the equation to find the -coordinate of the vertex. That's how you get your answer.

The line of symmetry is the center line of the curved line of the graph, separating it into two lines of equal length that curve at the same angle. If you fold the graph at the line of symmetry, both sides of the graph should meet perfectly. The line of symmetry need not be on point 0 of the x axis.
