What is the y-intercept?

Back

The y-intercept is the point where a graph intersects the y-axis. For the equation y = mx + b, it is represented by the value of b.

What is the minimum of a graph?

Back

The minimum of a graph is the lowest point on the graph. It represents the smallest value of the function.

What is a quadratic equation?

Back

A quadratic equation is a polynomial equation of degree 2, typically in the form y = ax^2 + bx + c.

Front

How do you factor a trinomial?

Back

To factor a trinomial of the form x^2 + bx + c, find two numbers that multiply to c and add to b.

Front

What does the vertex of a parabola represent?

Back

The vertex of a parabola is the highest or lowest point of the graph, depending on whether it opens upwards or downwards.

Front

What is the parent function of absolute value?

Back

The parent function of absolute value is y = |x|, which creates a V-shaped graph.

Front

What does it mean to transform a function?

Back

Transforming a function involves shifting, stretching, compressing, or reflecting the graph of the function.

Front

What is the effect of adding a constant to a function?

Back

Adding a constant to a function shifts the graph vertically. For example, y = f(x) + k shifts the graph up by k units.

Front

What is the effect of subtracting a constant from x in a function?

Back

Subtracting a constant from x shifts the graph horizontally. For example, y = f(x - k) shifts the graph right by k units.

Front

What is the standard form of a quadratic equation?

Back

The standard form of a quadratic equation is y = ax^2 + bx + c, where a, b, and c are constants.
