What is the elimination method in solving systems of equations?

Back

The elimination method involves adding or subtracting equations to eliminate one variable, making it easier to solve for the remaining variable.

Front

What does it mean for a function to be wider than another function?

Back

A function is wider than another if its graph has a smaller leading coefficient in front of the squared term, resulting in a more gradual curve.

Front

What is the discriminant in a quadratic equation?

Back

Front

What does a negative discriminant indicate about the roots of a quadratic equation?

Back

A negative discriminant indicates that the quadratic equation has no real roots, meaning the graph does not intersect the x-axis.

Front

What is the focus of a parabola?

Back

The focus of a parabola is a fixed point located inside the curve, which helps define the shape of the parabola.

Front

How do you determine the range of a function?

Back

To determine the range, identify the possible output values (y-values) of the function, often by analyzing the graph from bottom to top.

Front

What is the vertex of a parabola?

Back

The vertex is the highest or lowest point of the parabola, depending on its orientation (opening upwards or downwards).

Front

What is the standard form of a quadratic function?

Back

Front

What does it mean for a function to be increasing?

Back

A function is increasing if, as the input values (x) increase, the output values (y) also increase.

Front

What is the axis of symmetry in a parabola?

Back

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