Given f(x) = -4x - 10 and f(x) = 10, find x.

• x = -5

• x = 5

• x = -50

• x = 30

What is the value of x when f(x) = 16?

• x = 4 only

• x = 4 and x = 8

• x = 16

• Not on the graph

Describe the transformation

• left 2 up 5

• right 2 up 5

• left 2 down 5

• right 2 down 5

Is the graph a function? Why?

• Yes, it passes the vertical line test.

• No. The graph does not go on forever.

• No. The graph does not have a pattern.

• Yes, it has a domain and a range.

What type of function is shown?

• linear

• quadratic

• square root

• absolute value

According to the Algebra tiles, what are the factors? (FYI: ALL tiles are positive!)

• (x + 1)(x + 2)

• (x)(x+ 3)

• (x + 2)(x + 4)

• (3x)(x + 4)

Determine the equation for the line with a slope of -2 and a y-intercept of 5.

Given the length is (2x+3), which of the following expressions is equivalent to the area of the rectangle?

• (2x+3)(x+2)

• (x+3)(x+2)

• (2x+3)(x+7)

• (2x+3)(x+3)

According to the Algebra tiles, what is the area? (FYI: ALL tiles are positive!)

• x² + 8x + 4

• x² + 6x

• x² + 8

• x² + 6x + 8
