Graphing Transformed Parabolas

The video tutorial covers transforming quadratic equations by applying vertical stretches, flips, and shifts. It explains the roles of A, H, and K in these transformations and demonstrates how to graph transformed parabolas. Through examples, the tutorial shows how to create equations from graphs and solve for unknowns using vertex form.

How does the variable 'h' affect the parabola?

• It shifts the parabola left and right

• It stretches the parabola

• It flips the parabola

• It shifts the parabola up and down

What is the effect of the variable 'k' on the parabola?

• It stretches the parabola

• It shifts the parabola up and down

• It flips the parabola

• It shifts the parabola left and right

What is the first step in graphing a transformed parabola?

• Identify the vertex

• Shift the parabola vertically

• Shift the parabola horizontally

• Apply vertical stretch

How do you determine the new vertex after a vertical shift?

• Subtract 'h' from the x-coordinate

• Add 'h' to the x-coordinate

• Add 'k' to the y-coordinate

• Subtract 'k' from the y-coordinate

What happens to the parabola when 'a' is greater than 1?

• It shifts left

What is the vertex form of a quadratic equation?

• y = a(x - h)^2 + k

• y = ax^2 + bx + c

• y = ax + b

• y = a(x + h)^2 - k
