Exploring Transformations of Quadratic Functions

What is a necessary component for a function to be considered quadratic?

• It must have an x^3 term.

• It must have an x^2 term.

• It must have a constant term.

• It must have an x term.

Which of the following is NOT a quadratic function?

If 'a' is positive in the vertex form, how does the parabola open?

• To the left

• Downward

• Upward

• To the right

What effect does a negative 'a' value have on the graph of a quadratic function?

• It makes the parabola open downward.

• It makes the parabola open upward.

• It shifts the graph to the right.

• It shifts the graph to the left.

How does the 'h' value in the vertex form affect the graph?

• It changes the direction of the graph.

• It changes the width of the graph.

• It moves the graph left or right.

• It moves the graph up or down.

What transformation occurs if 'k' is positive in the vertex form?

• The graph shifts upward.

• The graph shifts to the right.

• The graph shifts to the left.

• The graph shifts downward.

Given the equation y = 3(x + 2)^2 - 4, what is the transformation if we translate it up 2 units and left 5 units?

• y = 3(x + 7)^2 - 6

• y = 3(x - 3)^2 - 6

• y = 3(x - 3)^2 - 2

• y = 3(x + 7)^2 - 2
