(3.8) HW: Quadratic Functions

Front

What is a y-intercept?

Back

The y-intercept is the point where a graph intersects the y-axis. It occurs when x = 0.

Front

Identify the y-intercept of the point (0, 4).

Back

The y-intercept is (0, 4).

Front

What does the ordered pair (0, -2) represent on a graph?

Back

It represents the y-intercept of the graph.

Front

What is the vertex of a parabola?

Back

The vertex is the highest or lowest point on the graph of a parabola.

Front

Find the vertex of the parabola represented by the point (4, 12.5).

Back

The vertex is (4, 12.5).

Front

What is the axis of symmetry in a quadratic function?

Back

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

Front

Determine the axis of symmetry for the function f(x) = x² - 8x + 15.

Back

The axis of symmetry is x = 4.

Front

What is the significance of the maximum value in a parabola?

Back

The maximum value is the highest point of the parabola, indicating the peak of the graph.

Front

Does the parabola represented by the function f(x) = x² - 8x + 15 have a maximum or minimum?

Back

It has a maximum value.

Front

What is the maximum value of the parabola f(x) = x² - 8x + 15?

Back

The maximum value is 5.
