AGS 2 - Unit 2 Test Day Practice

Front

Describe the graph of the function: f(x)=5(x-3)² +2

Back

Opens Upward and has a minimum value at (3,2)

Front

Given the equation: y = -\frac{1}{2}x² + 4x - 8, which statement is NOT true about its graph?

Back

The axis of Symmetry is x = -4

Front

Complete the Square and write in Vertex Form: f(x) = x² + 6x + 5

Back

f(x) = (x + 3)² - 4

Front

What are the x-intercepts of y = 2(x - 3)(x + 6)?

Back

(3,0),(-6,0)

Front

What is the y-intercept for the function y=2(x-3)²-2?

Back

(0, 16)

Front

What is the vertex form of a quadratic function?

Back

The vertex form is f(x) = a(x-h)² + k, where (h,k) is the vertex.

Front

What does it mean for a parabola to open upward?

Back

A parabola opens upward if the coefficient of the x² term is positive.

Front

How do you find the axis of symmetry for a quadratic function?

Back

The axis of symmetry can be found using the formula x = -\frac{b}{2a}.

Front

What is the significance of the vertex in a quadratic function?

Back

The vertex represents the maximum or minimum point of the parabola.

Front

How do you determine the x-intercepts of a quadratic function?

Back

Set the function equal to zero and solve for x.
