Quadratic Sequences and Functions

The sequence 5, 9, 13, 17, is ...

(select all answer that apply)

• a quadratic sequence

• a linear sequence

• neither a linear nor a quadratic sequence

The sequence 7, 22, 49, 88 ...

(select all answer that are correct)

• is a quadratic sequence

• has 5th term 139

• has 6th term 204

• is a linear sequence

Which of the following reasons can be used to support the claim that the values in the table show a quadratic relationship?

• The input values increase by the same value.

• As the value of x increases by 1, the first difference of y is the same value.

• As the value of x increases by 1, the second difference of y is the same value.

• As the value of x increases by 1, the second difference of y decreases by same value.

• h(x) = x² - 7x + 12

• h(x) = x² + 7x + 12

• h(x) = x² - x - 12

• h(x) = x² + x - 12

A quadratic function is defined by f(x)=⁢x² + 5x −24. Which of the following expresses f(x) as the product of two linear factors?

• f(x) = (x + 12)(x - 2)

• f(x) = (x - 8)(x + 3)

• f(x) = (x + 6)(x - 4)

• f(x) = (x + 8)(x - 3)

Expand and simplify: 4(3−w) + 5(w+2)

• w + 22
• 3w + 10
• 8 - w
• 2w + 18
