Front

What is a decreasing interval in a function?

Back

A decreasing interval is a range of x-values where the function's output (y-values) decreases as x increases.

Front

How do you identify the decreasing interval from a graph?

Back

Look for sections of the graph where the curve slopes downward from left to right.

Front

What is the solution to a system of equations?

Back

The solution is the point(s) where the graphs of the equations intersect.

Front

How do you find the solution to a system of equations graphically?

Back

Graph both equations on the same set of axes and identify the intersection points.

Front

What does it mean for a function to be transformed from its parent function?

Back

It means the function has been shifted, stretched, compressed, or reflected compared to its original form.

Front

What is the parent function of a quadratic equation?

Back

Front

What does 'right 5 down 1' mean in function transformation?

Back

It means to shift the graph 5 units to the right and 1 unit down from its original position.

Front

What is the significance of the vertex in a quadratic function?

Back

The vertex is the highest or lowest point of the parabola, indicating the maximum or minimum value of the function.

Front

What is the standard form of a quadratic equation?

Back

Front

How do you determine if a quadratic equation has no solution?

Back

If the discriminant (b^2 - 4ac) is less than zero, the equation has no real solutions.
