Co-Teaching Math 1 Module 2 Review

The graph of a quadratic function is called a:

• Parabola

• Circle

• Vertex

• Intercept

The vertex of the parabola below is a:

• Maximum

• Minimum

• Y-intercept

• X-intercept

The x-intercepts of the graph shown below are:

• -3 and 1

• 1 and 3

• 1 and 4

• 3 only

Find the x-intercepts of the quadratic function: f(x) = 2x² + 4x - 6.

• -3 and 1

• 1 and 3

• -1 and 3

• -1 and -3

Find the x-intercepts of the quadratic function f(x) = x² - 25.

• 1 and 5

• -25 and 25

• 5 only

• -5 and 5

Which function has the larger maximum? Function 1: The Table or Function 2: f(x) = -x² + 6x - 6

• Function 1

• Function 2

What is the difference in the y-intercepts of the two functions below? Function 2 - Function 1?

Function 1: the table

Function 2: f(x) = x² - 3x + 5

• 8

• -8

• 2

• -2

The width of a rectangle is 4 feet less than the length. If the area of the rectangle is 45ft², what is the length of the rectangle?

• 4 ft

• 5 ft

• 9 ft

• 7 ft

The function f(t) = -4t² + 17t + 42 models the approximate height of an object t seconds after it is launched. How many seconds does it take the object to hit the ground?

• 6 seconds

• 42 seconds

• 7 seconds

• 17 seconds

Solve using the square root method: 5x² – 125 = 0

• x = 25 and x = -25

• x = 10 and x = -5

• x = 8 and x = -8

• x = 5 and x = -5
