Graphing Quadratic Equations

Front

What are X-intercepts?

Back

X-intercepts are the points where a graph intersects the x-axis, meaning the value of y is zero.

Front

How do you find the X-intercepts of a quadratic equation?

Back

To find the X-intercepts, set the equation equal to zero and solve for x.

Front

What is the vertex of a parabola?

Back

The vertex is the highest or lowest point of the parabola, depending on its orientation.

Front

What is the formula to find the axis of symmetry of a parabola?

Back

Front

What are the coordinates of the y-intercept?

Back

The y-intercept is the point where the graph intersects the y-axis, found by setting x=0 in the equation.

Front

How do you determine the y-intercept from a quadratic equation?

Back

To find the y-intercept, substitute x=0 into the equation and solve for y.

Front

What does the term 'axis of symmetry' refer to in a parabola?

Back

The axis of symmetry is a vertical line that divides the parabola into two mirror-image halves.

Front

What is the significance of the coefficient 'a' in a quadratic equation?

Back

The coefficient 'a' determines the direction of the parabola: if 'a' is positive, it opens upwards; if negative, it opens downwards.
