Transformations of Quadratic Functions

Translation Example: The function y = (x + 5)² is derived from y = x² by translating the graph 5 units to the left.
Vertical Translations: The function y = x² - 7 represents a vertical translation of the graph of y = x² downwards by 7 units.
Wider vs. Narrower Graphs: The graph y = -0.2x² is wider than y = x² and opens in the opposite direction, while y = 5x² is narrower than y = x² and opens in the same direction.
Graph Equation Construction: For the function graph, use y = (x + ___)² + ___, with an example being y = (x - 5)² + 3, indicating a horizontal shift to the right by 5 and a vertical shift upwards by 3.
Horizontal and Vertical Shifts: To obtain y = (x - 8)² from y = x², shift right by 8. To convert y = x² to y = x² - 6, shift down by 6.
Projectile Motion Representation: A ball's height, modeled by y = -16x² + 32x + 3, describes a parabolic path. Completing the square reveals a vertex form indicating a reflection across the x-axis, narrower shape, and shifts to the right by 1 unit and up by 19 units.
Identifying Graph Type: The graph of y = -(x + 1)² - 3 is identified as the third graph option.
Finding Vertex Coordinates: The vertex for y = (x - 1)² - 5 is at (1, -5). For y = -4(x + 3)² + 2, the vertex is at (-3, 2).
Vertex Form Conversion Steps: Converting y = x² + 2x - 1 to vertex form involves forming a perfect-square trinomial, factoring it, and simplifying to (x + 1)² - 2.
Finding Vertex Form Parameters: The vertex form of y = x² + 6x + 10 results in y = (x + 3)² + 1 after identifying h = -3 and k = 1.
Converting to Vertex Form with Leading Coefficient: The function y = 8x² + 32x + 17 transforms to vertex form by first factoring out the leading coefficient, leading to y = 8(x + 2)² - 15.
Graph Properties Analysis: For f(x) = 6(x + 1)² - 9, the true statements include that the vertex is not (1, -9), the graph opens upward, the graph is steeper than y = x², and it is equivalent to f(x) = 6x² + 12x - 3.

This quiz focuses on transformations of quadratic functions, specifically how translations and dilations affect the graph of y = x².
