120524 Vertex Form Mastery Check PRACTICE

Front

Convert the equation y = x² + 4x into vertex form.

Back

y = (x + 2)² - 4

Front

Which of the following is the correct equation for the given graph? f(x) = (x - 2)² - 1, f(x) = (x + 2)² - 1, f(x) = -(x + 2)² - 1, f(x) = -(x - 2)² - 1

Back

f(x) = (x + 2)² - 1

Front

Which of the following shows f(x) = x² + 12x - 2 written in vertex form? f(x) = (x + 6)² + 142, f(x) = (x + 6)² - 34, f(x) = (x + 6)² - 38, f(x) = (x + 6)² + 34

Back

f(x) = (x + 6)² - 38

Front

What is the equation of this graph? f(x) = (x - 5)² + 1, f(x) = (x - 1)² - 5, f(x) = (x + 1)² - 5, f(x) = (x + 5)² + 1

Back

f(x) = (x - 1)² - 5

Front

The parabola y = x² - 2x + 4 will have a vertex of? (-1, 2), (1, 2), (-1, 3), (1, 3)

Back

(1, 3)

Front

What is the vertex form of a quadratic equation?

Back

The vertex form of a quadratic equation is y = a(x - h)² + k, where (h, k) is the vertex.

Front

How do you find the vertex of a parabola given in standard form?

Back

To find the vertex of a parabola in standard form y = ax² + bx + c, use the formula h = -b/(2a) and k = f(h).

Front

What does the 'a' value in the vertex form indicate about the parabola?

Back

The 'a' value indicates the direction of the parabola (upward if a > 0, downward if a < 0) and its width.

Front

What is the significance of the vertex in a parabola?

Back

The vertex is the highest or lowest point of the parabola, depending on its direction.

Front

How do you convert from standard form to vertex form?

Back

Use the method of completing the square.
